Description

201105755 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a reinforcing material for paving repair. [Prior Art] Various methods and composites for reinforcing asphalt roads and overlying layers have been proposed. Some people describe glass fiber grids impregnated with resin. In order to repair the old pavement, the asphalt viscous coating is applied along with the glass fiber grid, generally according to the construction specifications. The viscous coating is applied in liquid form (for example by spraying in the form of an emulsion or hot asphalt cement binder) and thereafter changed from a liquid to a solid. The viscous coating is applied to the installed grid. Above, and on the back of the grille, there is an adhesive coating used as an auxiliary for bonding the new asphalt pavement to the existing paving surface. To install a fiberglass grid when there is no adhesive coating on the back of the grid, first apply a viscous coating to the existing decking. The grid is placed on the viscous coating before the viscous coating is fully cured. As the viscous coating is further degraded, it holds the grid in place on the underlying surface. When the hot splatter concrete is overlaid on the grid, the viscous coating partially melts and fuses with the impregnated resin of the grid. Adhesive coatings have several highly desirable features that are convenient for use with such reinforcements. In particular, it is completely compatible with the asphalt concrete or cement to be used as the overcoat' and its fluid properties allow it to flow into the rough paving surface and smooth the surfaces. Another-side's adhesive coating presents several challenges. Viscosity coating properties are extremely sensitive to ambient conditions, especially temperature and humidity. These conditions can affect the curing temperature of the emulsion viscous coating and can prevent curing under severe conditions. In less severe conditions, the equipment used to lay up the cladding must wait until the viscous coating has cured, resulting in unnecessary delays. For example, viscous coatings are typically emulsions that are leached in water, which are often stabilized by surfactants. To demonstrate emulsion potential, the emulsion must be decomposed and water removed to lay the asphalt film. The water removal process is essentially an evaporation process that is controlled by time, ambient temperature and humidity. Environmental conditions are often unfavorable, resulting in ineffective or unacceptable delays in bonding. JP 05-31 5732 describes a asphalt film that can be used in place of a spray-type emulsion adhesive coating. A bitumen film is applied over the substrate and a heated bituminous material is placed over the film. The film is formed by attaching the asphalt emulsion to both sides of the mesh body and solidifying it. The base layer containing pebbles, sand, and the like and the base layer on the gravel are placed on the roadbed and compacted. The film is placed on the upper substrate and the heated asphalt material is laid on the film. Repeat the laying of additional film and asphalt layer on the leaching layer. The membrane softens due to the heat of the asphalt material and fuses into a single unit. Therefore, there is still a need to improve the interlayer between the paving layers. SUMMARY OF THE INVENTION In some embodiments, an reinforcement for asphalt pavement comprises: an open grid having parallel strands of up to v sets of sets, each set of strands having an opening between adjacent strands And the groups are oriented at a substantial angle to each other with the coating system # placed on the grid without closing the openings between the strands, wherein the coating is at the paving temperature, the paving pressure or Both are activated to form a knot compatible with the asphalt pavement, wherein the coating is non-tacky at ambient temperature and pressure and wherein the coating comprises about 50% or more of the resinous non-asphalt portion and About 5% or less of the asphalt component. In some embodiments, a method of reinforced paving is provided wherein a second 142388.doc 201105755 surfacing layer is placed over the first surfacing layer. An open grid is provided that includes at least two sets of substantially parallel strands, each set of strands having an opening between adjacent strands and the sets being oriented at substantially a right angle to each other. The coating is placed on the grid without closing the openings between the strands. The coating is activated at the paving temperature, the paving pressure, or both to exhibit plastic flow and form a bond that is compatible with the asphalt pavement. The coating is non-tacky at ambient temperature and pressure. The coating comprises about 50% or more of the resinous non-asphalt component and about 50% or less of the asphalt component. The grid is continuously deployed on the first surfacing layer while maintaining the individual strands of the grid substantially parallel aligned. The coating is activated by applying a second surfacing layer over the first surfacing layer. The second surfacing layer passes through openings in the grill such that the serpentine openings provide significant and substantial direct contact between the first surfacing layer and the second surfacing layer. Activation causes the coating to plastically flow to improve interlayer bonding between the first surfacing layer and the second surfacing layer. In some embodiments, a method of making a reinforcement for asphalt pavement comprises: providing an open grid comprising at least two sets of parallel continuous filament fiber strands "between adjacent strands There is an opening, and the two sets of strands are perpendicular to each other.

The coating comprises a thermoplastic resin that is plastically flowable at the paving temperature, the paving pressure, or both, but is non-tacky at ambient temperature and pressure. The coating comprises a non-asphalt material or a material comprising a majority or majority of the resinous non-asphalt component and about 50% or less of the asphalt component. A surface layer of asphalt is applied to the grid, the asphalt binder layer, and the surface of the existing road. The asphalt surface layer has a thickness of at least about 1.5 inches (40 mm). The thermoplastic resin is plastically flowed to improve interlayer adhesion between the asphalt binder layer and the asphalt surface layer. The shear strength is at least about 1 kN in a four-ply wafer comprising a grid, an asphalt binder layer, and an asphalt surface layer. In some embodiments, the product comprises a first non-woven polymer substrate and a second non-woven polymer substrate. The reinforcing fiber layer is sandwiched between the non-woven polymer substrates. The adhesive bonds the reinforcing fiber layer to the non-woven substrate.

In some embodiments, a strengthening product is formed. The method comprises the steps of: coating a layer of reinforcing fibers with an adhesive comprising 50-99% by weight of a PVc latex emulsion; and laminating the layer of reinforcing fibers to the first non-woven polymer substrate and the first non-woven polymer substrate . [Embodiment] The preferred embodiment of the present invention and other information related to the present disclosure 142388.doc 201105755 are described with reference to the accompanying drawings. The schema is considered to be one of the "lower", "upper", "horizontal t-embodimental embodiments of the entire written description, and is intended to be combined with the _--- (four) readings.

Sometimes single fibers or single filaments are also known as strands. Resin. Has a solid or pseudo-solid organic material with a relatively high molecular weight, which exhibits a tendency to flow when subjected to stress or temperature. In the thermoplastic form, it usually has a softening or melting range. Most resins are polymers. The words "paving road j, "road surface" and "surface" are used herein in their broad sense to include airports, sidewalks, Lanes, parking lots and all other such paving surfaces. Figure 1 shows an example of a paving section 150. During the maintenance and repair of the paving 1 5 ', the asphalt binder layer 135 is overlaid onto the existing old pavement 13〇, The old pavement 13 0 can be concrete, asphalt or a mixture thereof. The old paving 丨 3 〇 is usually textured or flattened by an abrasive roller (not shown) to provide a good susceptibility to the adhesive layer 135. A pre-formed resin film or a film impregnated with a resin is placed on the adhesive layer 135 and reinforced with the surface layer 14 。. This ensures interlayer bonding in the multilayer paving structure, which is reduced, for example, by a car. The stress distribution applied to the surface layer is necessary. The adhesive film 100 has a first main surface and a second main surface. The first main surface and the second main surface of the adhesive film 1 are made of a non-asphalt resin material. Or a composition comprising about 50% or more of a resin and about 5% or less by weight of the asphalt material. The material of the surface of the adhesive film is preferably not more than 25% of the material of the leaching material, and The material of the surface of the viscous film is more preferably not more than 2% by weight of the asphalt material. In some embodiments, the viscous film 1 〇〇 comprises a carrier substrate coated with a resin on the first major surface and the second major surface thereof a non-asphalt material, or coated on its first major surface and second major surface with a resinous non-geographic material containing about 5% or more and about 5 G% or less s material. In other embodiments, the entire viscous film 100 consists essentially of a resinous non-asphalt material composed of a resinous non-asphalt material; or the entire viscous film (10) is substantially composed of a resinous non-asphalt material of a large portion of the bulk material. And the material composition of the non-zero smaller portion of the asphalt material, or consists of a resin material comprising a larger or majority portion of the resinous (tetra) green material and a non-zero smaller portion of the asphalt material of 142388.doc 201105755. In some embodiments, the viscous film 100 is suitable for use as a substitute for a greening emulsion for use as a bonding agent between the surfacing layers 135 and 140. Adhesive film 1〇〇 Enhances the interlayer adhesion in the construction of asphalt roads. Since the viscous film 1〇0 is a prefabricated product, it allows the installer to control the application rate and thickness of the viscous layer. Spray and cure operations are eliminated when using viscous 臈1〇〇 (on the spot if a dip emulsion is used). The viscous membrane 1加快 accelerates road construction by removing these steps at the construction site. The viscous film provides a thickness equal to or better than that obtained with an asphalt emulsion and shear and fatigue properties. Figure 2 shows a first example of a viscous film which may be a composite film. In some embodiments, as shown in FIGS. 1 and 2, the polymer film 11 is coated on the base layer 135 and serves as a carrier for uniformly distributing the resin of the composite adhesive film (or contains about 50%). Or 50% or more of the polymer resin and about 5 % or less of the material of the asphalt material) 12 〇. Through the coating process, the resin 12 〇 (or the combination of resin and asphalt material) completely covers the sides of the carrier film 丨 1 以 to form a viscous composite film 100 ❶ coating non-stick and smooth surface properties provided on the construction site operation Convenience. An exemplary method of preparing the composite viscous film 100 is as follows. The first step involves laying a resin film or a resin film impregnated with the resin as the carrier film 10 . The film is then coated with a polymeric resin 120 (or a combination of a resin and a bituminous material), for example, by dipping the film 11 into a resin or a combination of a resin and a bituminous material. The coated film was then dried 1 Torr. An adhesive 122 such as a pressure sensitive adhesive may be applied to the back side of the coated film (the bottom side after mounting). J42388.doc 201105755 Subsequently, the adhesive 122 is dried. Adhesive 122 holds the film in place when the overlying surface layer 140 is applied. The polymeric resin (or combination of resin and asphalt material) 120 can have a coefficient of thermal expansion (CTE) similar to that of asphalt 140. Preferably, the polymeric resin (or combination of resin and asphalt material) has a higher stability than asphalts M0 and 135' and a higher hardness over a wide temperature range. The composite viscous mold 1 is more viscoelastic than the asphalt based film. When dry, the composite film 1 〇 has a smooth non-stick surface. In use, when the surface layer 14 of the hot mix asphalt mixture is applied to the viscous composite film 1 , the polymeric resin (or the coating composition of the resin and the asphalt material) 12 is activated to provide a bonding force. And the attachment between the surfacing layers 135, 140 is enhanced by means of the viscous composite film 1 。. ¥ When using asphalt spray emulsion in road construction, the installer must try to make the asphalt emulsion coating properly thin and uniform for optimum performance. The viscous film 1 as described herein is used to provide a predetermined thickness. The thickness of the coating 12 can be controlled to be uniform. The thickness of the coating 12 can be optimized to a thickness equivalent to the optimum application rate of the asphalt emulsion. The viscous film 100 removes the step of spraying and solidifying the asphalt emulsion on the spot. It can shorten the construction of the pavement (4) and reduce the cost of its people. In addition, because the on-site curing step is removed, the time required to complete a given paving area is more predictable than when using a spray emulsion. By eliminating the unpredictability of installation time, it is possible to eliminate the loose time in the Anshang time course, thereby increasing the efficiency, and the duration of the V-neck transition. In addition, since the film thickness can be optimized and controlled, the viscous medium consumption can be reduced. The ability to use prefabricated and mass produced composite viscous membranes provides an opportunity to reduce material costs. 142388.doc 201105755 In the second embodiment, the addition of the adhesive i 22 to the back of the viscous film 100 makes the field installation firmer. For ease of installation, a pressure sensitive adhesive 122 ° is preferably used. In the second example, the carrier film 11 may comprise a polyethylene film. The carrier can have a thickness of from about 0.5 mils to about 10 mils, and more preferably from about 0.5 back ears to about 2 mils. For example, the film 11 can be a low density polyethylene film of about mil (〇·〇1 mm), and other materials and thicknesses can be used, such as about 2 mils (〇.〇5 mm). Thick polyethylene_polypropylene copolymer film. Polyethylene is a cheap material. Although polyethylene may shrink at the drying temperature of some resin coating materials, it is preferred that the resin protective film be 〇1〇 so that the film retains its shape during drying. Other polymeric films compatible with bitumen can be used in carrier layer 110 (eg, PVC, nylon (polyamide), acrylics, HDPE, and certain polypropylenes to provide the desired rigidity and compatibility. And Corrosion Resistance) In other embodiments, the carrier layer can comprise a multilayer sheet of two or more of such materials or a combination of one of the materials and a different compatible material. The membrane 110 can be perforated. The perforation increases the rate at which the resin 120 is impregnated into the film 11〇. A mesh of resin (or a coating composition of resin and asphalt material) 120 may be formed on both sides of the film 110. The heat from the hot melt asphalt of the surface layer 14 is transferred to the lower (adhesive) asphalt concrete layer 135 through the bottom of the film no. In some embodiments, the non-asphalt resinous coating (or coating composition of resin and asphalt material) 120 applied to the film 110 is such that the viscous film 1 is more compatible with the surrounding asphalt layers 135, 140. This is achieved by carefully adjusting the chemical composition of the coating 12 to cause the resin to flow under the paving temperature, the paving pressure, or both. The composition of the coating 120 preferably has a glass transition temperature above 68-77 °F (20-25 °C), and preferably undergoes plastic flow at temperatures above about 120-140 °F (50-6 (TC)). Once the temperature of the asphalt pavement is reached, that is, about 265-32 (^ (130-160 ° 〇, the coating 120 may still flow even under extremely low pressure. In fact 'the construction pressure and surface applied by compaction) The weight of layer 140 may be such that a certain degree of flow is achieved such that it is at least partially and extremely tight, proximate to the surface. During installation, the typical temperature of surface layer 140 begins at about 250-320V (121-160 〇C)' and The temperature of the interlayer adhesive film is about 140-150 ° F (60-66 ° C). This is sufficient to heat the adhesive film 1 and the coating 120 on the film 110. This heat causes the coating 120 to flow. And the film 11 is relaxed and "iron out" to promote better mechanical bonding of the adhesive film 1 and the adhesive layer 135 and the surface layer 140 of the pavement 150. Due to any exposed aggregates, The chemistry of the coating 120 can also allow a certain degree of physics and/or the van der Waals attraction of asphalt or its analogues. Chemical bonding. Both physical and chemical processes improve the shear adhesion between the surface layer and the bonding layer, thereby improving the shear strength. Generally speaking, the thicker the coating 120, the better the shearing efficiency until the coating materials are A unique maximum. In another preferred embodiment, 'providing a method of reducing the bending moment in the asphalt surfacing layer. The method comprises preferably having about 0.75 inch (19 mm) or 0.75 inch (19 mm) or more. A thickness of the asphalt adhesive layer 135 is applied to the existing road surface 130. The composite adhesive film 100 is then applied to the asphalt adhesive layer 135. The film 1 may comprise polyethylene, ethylene vinyl acetate (eva) or other suitable A carrier layer 110 of a polymer. In the composite layer 100, a resinous non- 142388.doc 12 201105755 cyan coating (or a coating composition of resin and asphalt material) or a film i2 is placed on the carrier film 110. Or a film (hereinafter collectively referred to as "surface layer") 120 is activated (thermoplastic) at a paving temperature, a paving pressure, or both to form a bond with the asphalt pavements 135, 140. The surface layer 12 can be included in the paving Temperature, paving Force or both plastic flow, but no viscosity at ambient temperature and pressure (4). The financial method into the package (4) has a thickness of 5 忖 (4 〇 mm) or 1.5 吋 (40 mm) or more The asphalt surface layer 14 is coated on the composite adhesive film 100, the asphalt adhesive layer 135, and the existing road surface 130. The pressure and heat of the surface layer 140 cause the thermoplastic resin 12 to plastically flow to improve the asphalt adhesive layer 135 and the asphalt surface layer 14 Interlayer bonding between the crucibles. The interlayer adhesion can be an adhesive bond, a fusion bond, or a chemical (and/or van der Waals) bond or a combination thereof. In some embodiments, the surface layer 12 is an acrylic coating. In some embodiments, 'surface layer 120 can comprise a polyethylene (pvC) latex emulsion coating that comprises about 1 to 8 weight percent wax release agent' and an additive that is selected from the group consisting of: : Soluble polymers, ammonia, thickeners, carbon black, defoamers and plasticizers. A preferred PVC latex emulsion is commercially available

Noveon, Inc. (Cleveland, OH) Vycar® 460x63 Latex (Vinyl Emulsion) provides a very high degree of plasticity on the coated surface at paving temperatures above about 120-140 T (49-60 ° C) flow. PVC latex polymers and asphalt may also have an inherent degree of chemical adhesion. In some embodiments, the coating comprises 40-60% Vycar® 460x63 latex' and in some embodiments, the coating comprises at least about 40% Vycar® 46〇χ63 latex and up to about 20% greening material. In some embodiments, the layer 142388.doc 201105755 comprises 45-50% Vycar® 460x63 latex, and in some embodiments, the coating comprises at least about 45% Vycar® 460x63 latex and up to about 5% greening material. It is known that the Vycar® 460x63 is inherently rigid, especially in cold climates. This can create mounting problems as the coated film 100 is coated along the curve in the road. VyCar 846 〇 x63 also has less resistance to liquid water than other resinous candidates. Because of its relatively low solids content, it may be difficult to obtain the desired degree of absorption, and once absorbed, it may be more difficult to dry the fabric sufficiently. Thus, in some embodiments, the coating containing Vycar 846(R) 63 is formulated in such a way that the coating is softer and increases its solids content. The polymer in coating 120 can also be prepared from softer monomers. The water repellency problem can be solved by incorporating a wax additive (WHydrocer 145) in an amount of about 3-5 wt% of the dry coating. This wax release agent also has a tendency to slightly soften the coating. The solids content of the coating can be modified to from about 50% to about 60% by weight, desirably about 55% by weight. /. Or 55 wt% or more. In addition to such improvements to pvc latex, a soluble polymer (such as (5) coffee 5 14 W) in an amount of about 5-19% by weight of the dry coating can be introduced to provide more coating on the Pad roll. Coagulation time and re- (four) nature. Other water soluble polymers can be used, such as Michemprime polymers. To activate the soluble polymer, it is possible to add hydrazine to a pH of about 8 or 9. The atmosphere can also be used to activate any alkali soluble thickener in the composition. These thickeners may include the commonly available thick g ^ ^ , . Α ^ 4, and are preferably used in the inability to obtain the target % of the draw. From R0hrn d

Haas (PhiIade Iphia, PA) 142388.doc 201105755 ASE-60 or 6038A will be suitable for this application. A coloring agent (such as carbon black) in an amount of about 1% by weight and up to about 0.05 weight. An antifoaming agent such as NXZ or DEFO is suitable for this application. Finally, a plasticizer can be used to obtain the desired softness of the coating. Because ADMEX 3 14 is a non-volatile polymeric plasticizer and does not create an environmental or health hazard 'it is desirable' and the content of about 2-5 wt% causes a significant change in coating softness. Many alternative types of resins can be used for the surface layer 120 as long as it plastically flows at the paving temperature, the paving pressure, or both. The main examples are PVC, nylon, acrylic, HDPE & some polyethylene and polypropylene, and ethylene vinyl acetate (EVA), which provide the desired rigidity, compatibility and corrosion resistance. It can be applied using hot melt, emulsion, solvent, heat curing or radiation curing systems. In some embodiments, the viscous film 1 〇〇 comprises a multilayer film. For example, the carrier layer 110 can be a multilayer film having a surface layer coating 12〇 coated thereon. In other embodiments, the entire viscous film 1 is a coextrudate and the surface layer 120 is a resin film coextruded with the carrier layer 11 。. The material of the surface layer 120 may be the same as the material of the carrier layer 11A, may include the same main component as the carrier layer uo, or may have two main components different from the carrier layer ιι. When any such alternative resin material is used for the surface layer 12, an anti-sticking agent (for example, a wax, a synthetic polymer 'small amount of talc powder) may be included in the layer 12 to prevent the pure film HH from being stored in a spiral light form. And when it is pulled out of the grid 1 〇 during the subsequent expansion, it is very sticky. Assist: The master gentleman can also be included in the surface layer 20 on one side or both sides of the carrier layer 110. 142388.doc 201105755 The above composition is significantly compatible with the asphalt surface i 4 〇 and the adhesive layer 135. It is allowed to strongly bond with the viscous film 100 embedded in the asphalt concrete. The solid adhesion between the pavement layers effectively reduces the stress distribution of the traffic on the surface layer. This solution prevents slippage, cracking and delamination (called premature stress) caused or caused by lack of interfacial bonding. The coefficient of thermal expansion of the surface layer 120 approximates the coefficient of thermal expansion of the asphalt mixture. The surface layer 120 may avoid improper detachment at the interface of the film 100 due to discrete thermal behavior in the composite asphalt concrete. The enhanced interface condition provides an extended service life for the overlying surface greening layer 140 from significant road stress. An example is described above in which the carrier film 11A comprises a first material (e.g., a polymer such as polyethylene), and the film 110 is coated with a second material 12 (e.g., Vycar® 460x63 with an additive as described above). However, other embodiments are contemplated in which the film 11 〇 consists essentially of (or consists of) a non-asphalt resinous material (e.g., Vycar0 460x63 with an additive) used as a coating material i 2 如上 as described above. In such embodiments, the separate layer of coating material 120 may be omitted. Therefore, the adhesive film layer may be a composite film 100 or a homogeneous resin film. The choice of composite film or homogenous film and the choice of carrier film 110 material can depend on material cost, ease of manufacture, and availability of each material, which can be readily assessed by one of ordinary skill in the art at any given time. When impregnated and coated with a resinous coating or coextruded with the resinous film 120, the film 100 is preferably semi-rigid and can be rolled onto the core for easy transport to the installation in the form of a prefabricated continuous assembly. Location where it can be easily spread out continuously for quick, economical and easy integration into the road. 142388.doc -16- 201105755 For example [film 100 can be placed on a 15 inch (4.5 meter) wide roll, which has a single piece structure of 10G meters long or longer. Alternatively, the adhesive layer (3) may be covered by a number of narrower strips of the film 1GG, typically about five feet and 5 feet wide. Therefore, it is practicable to use this film 1G0 on all or substantially all surfaces of the adhesive layer 135, & cost-effective due to reduced labor. At the paving site, the film 100 is unfolded with the adhesive 122 facing down and laid down on the underlying 135. When the film (10) is coated, the underlying 135 is preferably about 40-140 Å (4.4-60). 〇» Spreading the adhesive film 1 黏 and adhering to a backing layer or asphalt bonding layer 135 having a thickness of preferably about 75 吋 (19 mm) or 0.75 吋 (19 mm) or more. In some embodiments, Place any overlying or asphalt surface layer 14 on the film 1 (10) such that the adhesive 122 (e.g., pressure sensitive adhesive) applied during manufacture of the film 100 stabilizes the film 100 sufficiently to render the film 1〇〇 resisting the action of the worker walking on it, the construction vehicle on which it is driven, and especially the movement of the paving machine thereon. Although the membrane 100 is semi-rigid, it is easy to lay flat. It has a very small or even no rewinding tendency. It is attributed to the proper selection of the adhesive and/or the surface layer resin. In some examples, as shown in Figure 1-2, the surface is reformed. The pavement 130 to be surface reformed, the base layer 135, the viscous composite membrane crucible, and the surface layer 140 are included, and are not independent. In other embodiments, the adhesive film 100 is applied to the adhesive layer 135, the independent reinforcing layer is coated on the adhesive film 1 , and the surface layer 14 is applied to the reinforcing layer 142388.doc 201105755 For example: 'The reinforcement layer can be (1) asGrid 8 products (such as 855〇, 85〇ι, 85〇2, 8512 grid) available from Saint Gobain Technical Fabrics. In other examples, as shown in Figure 3-6 The viscous film 1 is included in the integral composite reinforced interlayer 200, 300 or 4 。. The integral composite 2 〇, 300 or 400 comprises a viscous film layer 1 and a reinforcing layer 1 〇. In some embodiments The composite reinforcing interlayer is a composite 2〇〇 comprising a composite adhesive layer or a resinous adhesive layer above the reinforcing layer 10 (Fig. 3), and an adhesive which can be a hot-melt adhesive. 12 Bonding the viscous layer 1〇〇 to the reinforcing layer ι〇. The hot-melt adhesive can be pressure-sensitive or permanent. The bottom surface of the reinforcing material (the viscous film layer 1 具有) has Adhesives, such as pressure sensitive adhesives, hold the composite 200 in place when the surface layer is applied. In the configuration of Fig. 3, the hot-melt adhesive layer 12 bonds the adhesive film layer 1〇〇 to the underlying reinforcing layer 10, so the adhesive film layer 100 does not need its own adhesive layer 122. Further, the surface layer 14 is in contact with The top layer of the film layer 1 and the adhesive layer 122 are not required on the surface of the film 1 。. The adhesive layer 122 can be omitted from the viscous film 1 used in the composite material 200 of FIG. In some embodiments, the composite reinforced interlayer is a composite 3 包含 comprising a composite viscous film layer or a reinforcing layer 10 over the resinous viscous film layer 100 (FIG. 4). The viscous film layer 100 is bonded to the reinforcing layer by an adhesive 12 which is a hot-melt adhesive. To ensure that the composite material 3〇〇 is held in place when the surface layer 140 is applied, the viscous film 1 复合 in the composite material 300 includes an adhesive 122 as shown in FIG. 2 on its bottom surface (its contact Level 135). In some embodiments, the composite reinforced interlayer is a composite 400 comprising a pair of composite bonds 142388.doc • 18 · 201105755 or a resinous viscous 400 rigl A and a layer 00 between layers 00 (Fig. 5). It should be understood that the first carrier layer 1H) and the surface layer (3) film (10) may be a material used in a coating having 12 Å or a homogeneous film having a suitable material in the surface layer, wherein the homogeneous film There is no individual carrier layer 11 〇β Λ family in the complex 5 400, so that the adhesive film 12 which can be hot-melt adhesive β bonds the viscous film to the enamel layer 100 and the reinforcing layer 10. To ensure that the composite material_ is held in place when the surface layer 140 is applied, the bottom viscous film (10) of the composite material (which contacts the leveling layer 135) includes on its bottom surface a dot as shown in FIG. Agent 122. The top adhesive film layer (contact surface layer 14G) does not require an adhesive 122 on its surface. Adhesive 122 can be omitted from the top adhesive layer 1 . The reinforcement layer 10 can be any of a variety of reinforcement materials. In some embodiments, an open grid (shown in Figures 9 and 8B) comprising at least two sets of substantially parallel strands 21 (shown in cross-section in Figures 7 and 8) is provided as the strengthening layer 10. Each set of strands 21 includes an opening 丨 9 (Fig. 9) between adjacent strands 21, and the sthical groups are oriented at a substantial angle to each other (e.g., about 9 degrees as appropriate). In some embodiments the 'strengthening layer can be from Saint Gobain Technical

Fabrics' GlasGrid® products (eg 8550, 8501 '8502, 8511 or 8512 grid). In some embodiments the 'gate 10 preferably comprises a weft_insert warp knit' wherein the strands 21 are at about 90 to each other. Angle orientation, as shown in Figure 9. The opening preferably has a size of about 〇.5吋x〇.5吋 (12 mm χ 12 mm) or more, but the opening may also be about 1 X 1 忖. Although the opening 19 may be square, the dimensions "a" and "b" may be different, such as in the case of a rectangle 142388.doc -19. 201105755. In some embodiments, the non-asphalt coating 22 is disposed on the grid 1 without opening the opening between the strands 21, as best shown in FIG. The coating 22 is activated at the paving temperature, the paving pressure, or both to form a bond that is compatible with the asphalt pavement. The sigma coating 2 2 is non-tacky at ambient temperature and pressure, making it easy to construct at the construction site. Perform operations. In some embodiments, the coating 22 on the strand 21 is the same material as the coating 12〇 applied to the polymeric film 11〇 in the composite adhesive film. The large grid opening 19 shown in FIG. 9 allows the asphalt mixture 135 and/or 14 〇 to completely enclose the strands 21 of the yarn 20 or roving, and allows the viscous layer 1 〇〇 and the adhesive layer 135 and the surface layer 14完全 Complete and substantial contact between the two. The adhesive layer 100 is bonded through the openings 19 of the grid 1 to bond the layers 135 and 14 〇 to allow the stress from the paving surfaces 135, 140 to be substantially transferred to the reinforcing layer 1 or the like. The obtained composite grid material has a high modulus and a high strength to cost ratio, and its expansion coefficient is similar to the expansion coefficient of the road construction material, and it resists the used rice used for road construction and materials found in the road environment (such as road salt). . The grid 10 may be formed from strands or yarns 21 of continuous filament glass fibers, but other high modulus fibers such as poly(p-phenylene terephthalamide) polyamine fibers may be used, known as Kevlar. ®. The 2000 tex 2ECR^E glass yarn is preferred, but we can also use the weight of about 300 tex to about 5 〇〇〇. A preferred glass fiber yarn having a strand strength of about 560 lb/in (10 N kN/m) or 560 lb/in (1 〇〇 (four) (four) or more, and 5% or 5% when measured according to ASTM D6637 The following elongation at break. These strands have a mass of I42388.doc -20- 201105755 preferably less than about 22 〇z/yd2 (740 g/m2) and more preferably about 11 oz/yd2 (370 g/m2)/ The unit area is such that the strands having a low degree of twist (i.e., 'about one turn or less per turn) form a grid having a rectangular or square opening 19, one side (the size "a" in Fig. 9, The size of "b" or both) is preferably in the range of 3/4 吋 to 1 ,, but one side ("a", "b" or both) can also be used in the range of 1/8 吋 to ό吋. Grid opening 19. The grid 10 is preferably tied with a thin line 25 as shown in the figure or otherwise fixedly connected at the intersection of the strand and the longitudinal strand. This connection allows the grid 10 to retain its The grid pattern prevents the strands 21 from unduly spreading before and during the impregnation with the non-asphalt coating 22, and retains the opening 19, which allows the overlying layer to adhere to the underlying layer and thereby increase the final composite pavement The strength of the compound 1 。. The fixed connection at the intersection of the grid 10 also contributes to the strength of the grid 1 部分 because it allows partial force parallel to one set of strands 21 to be partially transferred to another group of parallel At the same time, this open grid construction makes it possible to use less glass per square yard and thereby obtain a product that is, for example, more economical than a closed woven fabric. I prefer to use about 8 ounces per square yard. (ounce) grille 10, but can also use 4 to 24 ounces per square yard. Although we prefer to use 7〇 to 5〇 denier polyester fine wire 25 or equivalent on warp-knit weft knitting equipment The splicing of the grid is done at the same time, but other methods of forming a grid of fixed joints at the intersections may be utilized. For example, a non-woven grid prepared with a thermosetting or thermoplastic adhesive provides suitable strength. Once the grid 10 is formed, and before it is bonded to the viscous film, I42388.doc • 21 · 201105755 is coated with a resin, preferably a thermoplastic resin 22. That is, the grid is pre-impregnated with a resin 22 Collapse. Select Μ 涂层 涂层 22 The viscosity is such that it penetrates into the strand 21 of the grid. Although the resinous coating 22 may not wrap each of the filaments 20 of the glass strand 2, the resinous coating 22 is generally in the strand The inside of the wire 21 is uniformly spread, as shown in Fig. 8. This dipping imparts a better semi-rigid property to the strand 2, and moderates and protects the strand 21 and the glass filament from water and salt in the road environment. The oil and other elements are decadent. The impregnation also reduces abrasion between the glass strands 2i or filaments 20 and the cutting of one glass strand 21 or filament 20 by another glass strand or filament. The impregnation also reduces the tendency of the glass fibers to cut into each other after the grid has been laid, but before the coating 140 is applied. The grid should preferably have a range of about 25 kilonewtons per meter (kN/m), more preferably about 50 kN/m, and most preferably about 1.00 kN/m or more than 100 kN/m in the direction of each set of parallel strands. The minimum elongation 'and preferably less than about 丨〇% and more preferably less than 5 〇/〇 of elongation at break. When the preferred resinous coating 22 on the grid 10 is dried or cured, the strands 21 can be somewhat flattened but retain the opening i9. For example, in a preferred embodiment using a 2 roving, a rectangular grid 1 〇 ' having an opening 19 of about 3/4 吋 ^ 吋 ^ = b = 0.75 吋) can be formed and the roving is changed It is about 1/16 inch (1.6 mm) to 1/8 inch (3.2 mm) wide. The thickness of the roving after coating and drying may be about 1/32 inch (0.8 mm) or less than 1/32 inch (0.8 mm). The preferred frit of the fiberglass k-line is an uncoated GlasGrid® product (eg 855〇, 8501, 8502, 8511 or 8512 grid) available from Saint-Gobain Technical Fabrics. 142388.doc -22· 201105755 A number of resins can be used to impregnate the grid 10 as long as it plastically flows at the paving temperature, the paving pressure, or both. The main examples are pvc, nylon, acrylic, HDPE and certain polyethylene and polypropylene, which provide the desired rigidity, compatibility and corrosion resistance. It can be applied using a hot melt, emulsion, solvent, heat cure or radiation curing system, such as a coating containing a pvc emulsion such as vycar® 460x63. The PVC emulsion may also comprise about 18% by weight of a wax release agent, and one or more of the other additives selected from the group consisting of soluble polymers, ammonia, thickeners, carbon black, and Foaming agent and plasticizer. Any material suitable for use as the coating 12 of the composite polymer film 1 (such as any of the materials described above) can be used as the coating 22 of the grid 1 . In some embodiments, coatings 120 and 22 are the same material. In other embodiments, coatings 120 and 22 are of different materials, wherein each coating 12, 22 is compatible with the asphalt and can be activated by heat and/or pressure. Coatings 120 and 22 can be activated by pressure, heat or other means. When the surface of the pressure-applied resin is brought into contact with the second untreated surface and pressure is applied, the pressure activates the resin to form a bond. When the surface coated with the heat-activatable resin is brought into contact with an untreated surface and heat is applied, the heat-activatable resin forms a bond. The coatings 120 and 22 are preferably non-tacky at ambient or ambient pressure, as compared to other adhesives that are tacky at ambient temperatures (e.g., about 72 Torr) and ambient pressure (e.g., about 1 atmosphere). It only becomes sticky under approximate paving pressure or temperature. In most applications 'coating 12 〇 and 22 until reaching a coating temperature of about 120-140 ° F (49-60 ° C), or coating about 5 吋 (25_38 mm) or 1-1_5 吋 (25 -38mm) above the surfacing layer, or both at the same time 142388.doc •23·201105755 square plastic flow or adhesion. E-giass fiber has a glare of about 1800-1832T (about 1000 Å, which ensures stability when subjected to excessive heat of the paving operation. Shear strength between the surface layer 140 and the adhesive layer 135 It is desirable to be as high as possible, and the Nuech strength needs to be quite large over the extremely wide temperature range experienced by the grid 10. The viscous membrane-grid composites 200, 300 can be applied at ambient temperatures as low as about 40 °F. Or 400 is installed on the paving underlay and may be coated with asphalt concrete at a temperature of about 25 〇 320 ° F (121-160 ° C), typically about 300 ° F (149 ° C). The temperature of layer 22 rises to about 15 〇卞 (66 ° C) ° so 'we prefer that coatings 120 and 22 have about 66-7 7 °F (2 0-25 X:) or 66-77 ° F (20 -25 ° C) above the melting point or glass transition temperature Tg, and preferably at about 120-140 ° F (50-6 (TC) or more, plastic flow under typical pressure applied by paving. Once it reaches about 265-30 〇T (130-15 (TC) temperature, even under very low pressure, it is possible to flow, such as when coating an extremely thin asphalt layer. This allows the coatings 120 and 22 to plastically flow to improve the grid Passing in 1 Shear strength between the surface layer 140 and the adhesive layer 135 around the grid 10. The viscosity of the coatings 120 and 22 should have sufficient fluidity to flow onto the grid, but preferably has sufficient viscosity to allow for coating Or does not flow out of the grid or flow through the grid during storage, but actually remains on the grid.

For example, it can be placed on a 5 呎 5 ft wide report. The rolls contain a one-piece structure of 1 或 or longer. The mounting procedure of the viscous membrane-grid composite 200, 300 or 400 can be the same as described above for the independent viscous membrane 1 〇 。. Therefore, it is practicable to use this viscous membrane-grid composite 2 〇〇, 3 〇〇 or 4 所有 on all or substantially all of the paving surfaces. It can also be used to strengthen localized cracks 231 (Fig. 6), such as expanded joints. Although the grid 10 is semi-rigid, it is easy to lay flat. After it has been deployed, it has a very small or even no rewinding trend. It is believed that this is due to the proper selection of the binder and/or coating resin and the strengthening of the strands in the grid 1 , preferably glass. The large grid opening 19 shown in Figure 9 allows the asphalt mixture to completely enclose the strands 2 of the yarn 21 or roving, and allows the composite to be twisted, passed, and bonded to the adhesive layer 135 and the surface layer 14 Complete and substantial contact. The surface layer 140 is preferably placed at a thickness of about 1 < 5 pairs (4 mm) or i 5 pairs (4 mm).

In summary, it can be recognized that the self-adhesive adhesive film can be used alone or in combination with an open grille and a resinous coating for the reinforcement of asphalt paving, which is used for paving temperature and paving pressure. Or both to activate to form a bond that is compatible with the asphalt-paving. Example 2 Preparation of a film coated with a polymer resin A film of a blend of polyethylene (PE) and polypropylene (PP) having a thickness of 12 μm was prepared. The film was perforated every 25.4 times; the rice was spaced apart to have a 5 mm diameter opening to transfer heat from the hot mix asphalt mixture of the coated surface layer to the lower leachate layer and to adhere the film to the asphalt surfacing layer. The film was immersed in a bulk polymerized (vinyl chloride) pvc acrylic copolymer in the form of a litre liquid at 2 TC, and the coated film was dried in a convection oven for 2 minutes at 〇C until a square foot per square foot was reached. Residual rate of 123 grams of coating on the film. The film is preferably a synthetic material with a polymeric resin that is strongly adhered to the indigo system.

System 201105755 is available. Each film was placed in a sample including two greening layers and sheared at a constant displacement rate of 1 mm per minute. A pressure sensitive adhesive i ι can be applied to the bottom of the grid 10 during manufacture of the grid 10 or composite product 200 to facilitate installation, and after installation, the grid 1 is the bottom layer of the composite 200. The type of the adhesive 1 1 may be different from the hot-melt adhesive 12 for attaching the precoated film 100 to the grid 10. If the house-sensitive adhesive 11 is present, it is activated by applying pressure to the surface of the film 100 coated with the polymer resin of the composite 200. If a pressure sensitive adhesive 11 ’ is used, substantial force may be required to spread the film; a tractor or other mechanical means may be used. Adhesive 11 is preferably a synthetic material and can be applied to the precoated film in any suitable manner, such as by using a latex system, a solvent system, or a hot melt system. In a preferred latex system, the adhesive mash is dispersed in water, printed on the film using a gravure roll, and dried. In a solvent system, the adhesive is dissolved in a suitable solvent, printed on a film, and then the solvent is evaporated. In the hot melt system, the adhesive is melted in a reservoir, coated on a roll, and metered onto the roll with a tightly controlled knife edge to form a uniform film of liquid adhesive on the roll. The grid 1〇 is then brought into contact with the rolls and the adhesive is transferred to the bottom of the grid 10. Such coating methods are merely illustrative, and other methods of applying adhesives using latex, solvent or heat dampening systems can be readily selected by those skilled in the art. Example 3 Figure 11 is from the coating 120 and / or a graph of data from one of the tests performed on the composition used in coating 22. The data is used to determine the percentage of the domain-fixed bitumen emulsion that can be combined with the non-asphalt resinous material used in the coating 120 142388.doc -29- 201105755 without shearing performance relative to the shear performance of the non-resinous coating. Substantial degradation. The bidet emulsion was blended with the polymeric resin described in Table 1, in relative amounts as a percentage of dry weight. Blend resin was prepared using 6 different resin/asphalt ratios: polymer / bitumen (100% resin, 75:25, 50:50, 25:75, 10:90, 〇:1〇〇) 〇 uncoated Electronic grade glass grid fabrics (referred to as "original embryos") are manually immersed in a resin or resin/asphalt mixture and fully impregnated and dried. The manually coated fabric was placed between a pair of asphalt discs (a cylindrical sample of four turns in diameter). The wafers were constructed from asphalt mixtures from 75 standard compact Marshall compactors at 146 °C according to ASTM D6926-04. The shear performance test was carried out by means of a direct shear test. The shear strength as shown in Figure 11 varied from 1 kN for a pure asphalt coating to 3.68 kN for a 100% non-asphalt resin. Based on the curve of the fitted data points, the shear strength is about twice the shear strength of the individual asphalt emulsion at about 3% resin. At about 50% resin, the shear strength is about 2.4 times the shear strength of the telling emulsion. The shear strength at about 75% resin is about 3.5 times the shear strength of the green emulsion. At about 80% resin, the shear strength of about 3.5 kN is almost as high as the shear strength (about 3.7 kN) of the 100% polymer resin. Therefore, about 75. The mixture of /about to about 80% resin provides almost all of the strength of the 100% resin coating while providing greater economy. Therefore, if a blended coating is to be used, the material for the surface layer 120 of the adhesive film 1 preferably comprises 50% or more of a non-asphalt polymeric resin blended with the asphalt emulsion. 142388.doc -30· 201105755 Figure 12-14 shows another example. 12 shows a product 5〇〇 comprising a first non-woven polymer substrate and a second non-woven polymer substrate 5〇1, a reinforcing fiber layer 51〇 sandwiched between non-woven polymer substrates 501, and An adhesive 5 12 that bonds the reinforcing fiber layer to the non-woven substrate. The mesh or scrim 5 1 黏 is bonded to the substrate 501 and made into any of a variety of widths and/or lengths. In some embodiments, substrate 501 can comprise a polyester nonwoven woven cotton web.

These polyester nonwovens are commercially available from Shalag Shamir Non-wovens (Upper Galilee, Israel). In other embodiments, the substrate 501 can be a polyethylene non-woven felt, but other materials such as a polyethylene-polypropylene copolymer can also be used. Other polymers compatible with asphalt can be used for the substrate 501 (e.g., PVC, nylon (polyamide), acrylic, HDPE, and certain polypropylenes to provide the desired rigidity, compatibility, and corrosion resistance). In other embodiments, substrate 5〇1 may comprise a multilayer sheet of two or more of such materials or a combination of one of the materials and a different compatible material. The reinforcing fiber layer 5 10 comprises a fiberglass mesh or a scrim comprising at least a first set of yarns oriented substantially in the machine direction.

Referring now to Figure 12, in some embodiments, the product comprises a woven or scrim 510 of reinforced fiber coated yarn (e.g., fiberglass) and two woven non-woven substrates 501. The glass fiber mesh fabric or the scrim 510 is formed by "turbine technology". Turbine technology involves the use of a lateral (four) rotary (four) wheel head and an inhibitor (four) rotation mechanism to control the lateral spacing of the yarn. Subsequently, the glass fiber scrim 5H) was impregnated and coated with a binder. Many are difficult to use for the adhesive as long as it flows at the paving temperature, the paving pressure, or both. In some embodiments, the adhesive is in the above table!

In other embodiments, the adhesive may be acrylic, PVC, nylon, HDpE, and certain polyethylene and polypropylene, which provide the desired rigidity, compatibility, and corrosion resistance. Adhesives can be applied using hot melt, emulsion, solvent, heat cure or radiation curing systems. Immediately after the yarn is coated with the adhesive, the scrim 5 10 is laminated to the two polyester substrates 5 〇 j using an adhesive 512. In some embodiments, the adhesive 512 and the adhesive are both the same PVC latex emulsion as described in the above table, and a single coating step is used with the adhesive/adhesive &> beech yarn and the adhesive 5 12 Coating the yarn for the dust step. In other embodiments, the adhesive 512 can be applied independently of the step of impregnating the yarn 51 with a binder. For example, if the binder and the adhesive 512 are different materials from each other, a separate adhesive coating step is used.

After coating the mesh or scrim 51, the product is then cured (e.g., in the drying section of the machine) and wound into a finished roll. A glass fiber scrim 510 is obtained by sandwiching a top layer of a polyester non-woven substrate with a top layer of 5〇1 and a bottom layer of 5〇 J M2388.doc •32·201105755. Figure 14 shows an example of a device for preparing the product of Figure 12. The top substrate and the bottom substrate 501 are fed from a roll 552, which may be a polyester nonwoven material. The direction of the substrate 501 can be controlled by the feed roller 558 to control the fiberglass scrim 51 through a container fed by another roller 558 and through a coating 512 containing a coated scrim 51. The coated scrim 510 is leached from the coating container and redirected by one or more rollers 560,561. The top non-woven layer 5〇1 and the coated scrim 510 are then passed under the first laminating roll 554 while maintaining the tension between the second lamination roll 556 and the roll 561, thereby making the scrim and top non-woven Layer 501 is joined. The top non-woven layer 5〇1 is then fed together with the scrim 510 laminated thereto through another laminating roll 556 which causes the bottom non-woven substrate 501 to bond with the bottom of the scrim 51 to form a product 500.
