Definitions
- the present invention relates to the technical sector of works public, more specifically that of the construction and maintenance of roads, motorways, roadways, roadways and the like.
- the roadways are coated with a layer of hydrocarbon materials often called “coated”, or “concrete bituminous ", this product from an oil residue (asphalt). More specifically, the roads are in the general case (but not limiting) constituted by the support, generally a “coated”, a layer emulsion above the support, as a bonding layer, a reinforcement of the type of the invention above, and finally a new layer asphalt about 4 to about 25 cm thick, in one or more layers separated by a thin layer of bonding emulsion.
- bitumen such as textile reinforcements (FR A 2 592 411, FR A 2,635,542), fiberglass webs, grid structures, or complex reinforcements associating a grid and a nonwoven web.
- ROADTEX and "ROTAFLEX” (brands of the company CHOMARAT).
- ROADTEX type structures consist of an open grid of continuous glass filaments linked by a thermoplastic polymer.
- ROTAFLEX type structures are constituted by a polyester nonwoven reinforced with a glass grid.
- an aqueous bitumen emulsion is deposited on the pavement, then the bilayer structure, then a new layer of bitumen. It is specified that the polypropylene of the grid undergoes a treatment thermal during manufacture, to avoid shrinkage during impact thermal caused by the asphalt deposition temperature.
- the laminate is characterized in that the fabric is combined with the mesh plastic only at the thicker junctions of the mesh and not at the level of the strands of the mesh.
- this adhesive coating can be activated by heat or pressure and forms a bond between the grid and the asphalt.
- This adhesive does not, however, bond the two layers of asphalt on both sides of the grid, which may also be suitable for certain road applications.
- USP 3,581,631 (Enka Corp.) describes an armature which consists of a film comprising threads or filaments, forming meshes which are completely or partially clogged with an adhesive.
- This adhesive is selected from certain resins and certain polymers having a point softening above 50 ° C and is poured hot onto the film. The adhesive, on the one hand wets and "permeates" the film, and on the other hand is miscible with the bitumen layer.
- the first problem is the need to stick perfectly between them the different layers forming the structure, that is to say the support (often a mix), the reinforcing reinforcement and, in general, an upper layer (often a hot applied mix overall ).
- bitumen emulsions are produced in plants, and consist of liquid or semi-liquid aqueous emulsions applicable by usual gear. These emulsions can break as well in 5 minutes than several hours, depending in particular on the temperature prevailing at the application site. We adapt as best as possible the quality of the bitumen for the season and the region, but we cannot not produce a different batch for each site temperature.
- the object of the invention is to limit the rise of bitumen to through the mesh of the grid type reinforcements.
- bitumen it would be economically advantageous to reduce the amount of bitumen to be used.
- a grid product such as ROADTEX
- a conventional emulsion layer water and bitumen in a weight ratio of approximately 40 - 60%
- a grid + nonwoven product such as ROTAFLEX 833
- a nonwoven at 80 g / m 2 is used .
- an objective is to be able, despite a complex structure comprising a nonwoven, to reduce the rate of residual bitumen to values of 300 g / m 2 or even 200 g / m 2 , that is to say - say below the usual dosages of the bonding layers. This reduction contributes to the reduction of the bitumen rise.
- the invention resides in the combined use of a fusible product.
- the invention accelerates thanks to a basic treatment the speed of breakage or rupture of the emulsion of bitumen, which reduces the downtime of the site and the ascent bitumen (which is viscous) through the grid.
- the invention applies to any road structure in the broad sense, including including areas, runways, airports, etc. with at least one binder hydrocarbon, in particular so-called bituminous structures, in particular, but for representative purposes only, structures comprising at least a layer of asphalt or asphalt.
- the invention therefore provides a three-layer structure where the nonwoven is only partially blocked by the fusible product in order to limit the rise of bitumen.
- the fusible product performs a second function, that of bonding layer for the final bitumen layer (hot mix) which will be applied later on the assembly, which allows significantly reduce the dosage of bitumen emulsion.
- a preferred manufacturing process consists in preparing the fine nonwoven, and in "dusting" the fusible on the nonwoven.
- dusting means that, by any means of application known to those skilled in the art, the fusible is deposited so as to cover only part of the surface of the nonwoven. The dusting should be as regular as possible, but perfect regularity is not necessary.
- part of the surface is meant the fact that about 30 to 70% of the surface of the nonwoven is covered.
- fine nonwoven is meant a nonwoven of the order of 20 to 80, preferably 20 to 50, preferably 20 to 30 g / m 2 .
- the fusible product will be an EVA (ethylene / vinyl acetate) copolymer.
- the grid is then deposited on the face of the nonwoven having received the fusible.
- the complex according to the invention is available. so that the grid forms the underside and the nonwoven faces higher.
- the grid / nonwoven assembly traps an air film which will act as a heat shield against the cold temperature of the lower support, and will therefore optimize the fusion of EVA by heat brought by the deposition of the upper asphalt layer.
- the nonwoven will preferably be a hydrophobic fine nonwoven, of the polyester or polypropylene type, or glass nonwoven, in particular at about 20 - 50 g / m 2 , or even up to 80 g / m 2 .
- the nonwovens of the prior art are used at around 120 g / m 2 .
- This nonwoven must be mechanically degraded by punching by the aggregates contained in the mix, due to the gravity and compaction (see Fig. 3).
- open grid we mean a mesh grid wide compared to the granules contained in the upper layer asphalt.
- the mesh of the products will preferably be 5 x 5 mm; 10 x 10 mm; 30 x 30 mm; 40 x 26 mm; 50 x 50 mm.
- a mesh 40 x 26 will be preferred.
- the invention also relates to a method and a frame. allowing to break the bitumen emulsion more quickly.
- the structure according to the invention will be impregnated, either the grid / nonwoven assembly, or, most preferably, the nonwoven deposited on the grid, by a basic agent.
- the basic agent will be any agent or mixture of agents capable of give the structure a basic character sufficient to accelerate significantly the "breakage" of the emulsion, as for example the soda ash.
- the emulsion can thus be "broken” almost instantly or instantly. This additional measure allows to save the site a lot of time when setting up work, in particular by not making the teams wait unnecessarily.
- Any basic agent or any mixture of agents may be used basic capable of, or adapted to, meet the case-breaking criterion of the emulsion. Such products will be within the reach of the skilled person.
- the agent basic acts on the emulsion and provokes in an effective, simple and practice, breaking or breaking this emulsion. Without wanting to be linked by any theory, the Applicant considers that the agent basic deactivates the acid sites of the surfactants used to maintain the stability of the emulsion.
- Figure 1 depicts a typical road structure when one incorporates reinforcement.
- a layer of leveled pebbles 2 we deposits a thin bonding layer (emulsion) 3 then a layer of asphalt 4 which forms the "serious bitumen".
- This layer will receive the wearing course 5 which is composed, in its simplest form, a thin layer of emulsion 6 on which the reinforcement 7 is placed, after which the final coated layer 8 is deposited.
- One or more coats are applied above the grid of asphalt 8 superimposed, depending on the type of road structure.
- the the highest asphalt layer is called the wearing course.
- the asphalt layers are then linked together by a thin layer Layer 6 attachment type.
- the invention also applies to such variants.
- Figure 2 shows the order of arrangement of the elements according to the invention.
- the bonding emulsion 6 is deposited on the serious bitumen 4.
- This emulsion in accordance with an important advantage of the invention, will preferably be dosed with only 200 - 300 g of residual bitumen per m 2 .
- the complex 7 according to the invention is then deposited, for example manufactured as described above.
- This complex consists of the grid 22 and the fine nonwoven 20, the latter carrying on its underside the fusible 21.
- the asphalt layer 8 is then deposited (or the first layer if there must be several), which contains pebbles 23.
- the temperature means that the water in emulsion 6 can escape.
- Figure 3 shows the final state of the road structure, after the sequence shown in Figure 2.
- the stones 23 of the asphalt 8 have entered between the strands of the grid 22, through the fine nonwoven 20, and if necessary by tearing it, possibly until contact with the bonding layer 6 which has itself been at least softened by the heat and therefore at least partially integrated into the whole.
- the invention also relates to a method for reinforcing road structures characterized in that it is deposited on the layer bitumen emulsion covering the serious bitumen a reinforcement such as described above, then a coating layer, and also, as particular variant of implementation, the method of reinforcing road structures described above characterized in that one deposits one or more top layers of asphalt, each layer being bonded by an intermediate layer of bitumen emulsion.
- the invention relates in particular, according to one embodiment preferred, the method of reinforcing road structures which consists to unwind the complex prefabricated reinforcement according to the invention on the emulsion layer covering the serious bitumen.
- the various can also be run separately on the site elements of the complex frame.
- We can notably unroll the grid then the nonwoven carrying the “powdered” fusible or deposited in film openwork on its underside.
- the nonwoven may have been impregnated with beforehand by a basic agent, or include a basic agent in the mass. You can also incorporate the basic agent into the fusible deposited on the nonwoven. Finally, we can deposit a basic agent on the grid or on the nonwoven as it is unrolled.
- the invention also relates to a method for reinforcing road structures characterized in that at least one asphalt layer on the reinforcement, or characterized in that one deposits several layers of mix on the reinforcement, each layer being separated by a bonding layer of bitumen emulsion.
- the invention also relates to a method for reinforcing road structures, characterized in that an emulsion containing 200 - 300 g / m 2 of residual bitumen is used as the lower bonding layer of bitumen emulsion.
- the invention also relates to a method reinforcement of road structures according to which we use a no woven (possibly alone on certain sites) or any type of complex grid-type reinforcement, possibly including a no woven or similar structure, characterized in that said non is worn woven, or one or more of the elements constituting the complex of the type grid at a basic pH capable of accelerating breakage or rupture of the lower bitumen emulsion.
- a no woven possibly alone on certain sites
- any type of complex grid-type reinforcement possibly including a no woven or similar structure, characterized in that said non is worn woven, or one or more of the elements constituting the complex of the type grid at a basic pH capable of accelerating breakage or rupture of the lower bitumen emulsion.
