Description

Pavement method of a road on the bridge by using modified sulfur binder}

The present invention relates to a bridge packaging method, and more particularly to a method for packaging the bridge using a modified sulfur binder having properties that can be remelted at a temperature of 100 ℃ or less.

Sulfur is one of the nonmetallic elements, and there is also natural sulfur. However, sulfur is frequently generated during desulfurization of crude oil and natural gas.

Many studies are being conducted to apply sulfur generated in the desulfurization process of crude oil or natural gas to various industrial fields, rather than simply treating it as industrial waste.

In particular, in recent years, a technique for improving the performance of construction materials by using sulfur in place of or in combination with conventional construction materials has been developed and used.

However, the physical properties of sulfur dissolve at temperatures above 119 ° C and have solid properties at room temperature.

In addition, there is a problem that the flash point is 207 ° C, and the spontaneous ignition temperature is 245 ° C, which causes flammability. Therefore, the flash point is difficult to be used in various industrial fields such as construction materials.

Various techniques have been developed to remedy these disadvantages, but there are disadvantages such as difficulty in controlling the physical property reaction of sulfur and rapid solidification at room temperature, thereby preventing shaping.

Although many research and development efforts have been made on modified sulfur binders, which have improved properties by adding various materials to sulfur to improve the disadvantages of sulfur in various industrial fields, the reaction is difficult to control and rapidly solidified at room temperature. It does not have the disadvantages.

In this regard, the present applicant filed a patent application (Korean Patent Application No. 10-2007-0062430) on June 25, 2007 regarding a modified sulfur binder and a method of manufacturing the same, which can overcome the problems of the conventional modified sulfur binder.

First, the description of the present invention uses the term bridge pavement, but such a bridge pavement includes not only the pavement made in the upper plate of the bridge but also the case where the pavement is carried out on a structure other than the ground.

On the other hand, with reference to Figures 1 and 2 will be described for an example of the cross section of the cross-section pavement according to an embodiment of the present invention.

First, Figure 1 is a cross-sectional view showing a cross-section of a conventional cross-section pavement, Figure 2 is a cross-sectional view showing a cross-section of a cross-section pavement according to an embodiment of the present invention.

First, referring to the cross section of the conventional cross-section pavement with reference to Figure 1, the conventional cross-section pavement cross section is the structure 100, the adhesive layer 1 (110), the waterproof layer 120, the adhesive layer 2 (130), the base layer 140, the tack coating layer 150 and the surface layer.

The structure 100 is generally a concrete structure or a steel structure as the top plate of a bridge.

The adhesive layer 1110 is a layer formed to increase the adhesion between the waterproof layer 120 and the structure 100, and the waterproof layer 120 prevents rainwater or the like from directly penetrating the structure.

The adhesive layer 2 (130) increases the adhesive strength between the waterproof layer 120 and the base layer 140, and after forming the adhesive layer for increasing the adhesive strength of the waterproof layer 120 and other layers with the waterproof layer for protecting the structure, the base layer ( 140), the tack coating layer 150 and the surface layer 160 are constructed.

The base layer 140 is a layer that supports the surface layer 160 and distributes and reduces loads and impacts and transfers them to a roadbed or a structure.

The base layer 140 is formed by adding other materials, such as asphalt or cement, to the aggregate, such as crushed stone, sand, or stone powder, to be compacted with a roller.

Meanwhile, the tack coating layer 150 is a layer formed only when the surface layer 160 is formed of asphalt concrete, and is formed according to a construction method on a specification called a tack coat. ) And the adhesion between the surface layer 160.

The surface layer 160 is a layer that forms the surface of the road, and asphalt concrete, cement concrete, resin, and the like may be largely used depending on the forming material thereof.

Asphalt concrete pavement may be classified into gus asphalt pavement and rolled asphalt pavement depending on the material or construction method of the asphalt concrete used for the surface layer 160. It is obvious to those skilled in the art.

In addition, cement concrete pavement may be divided into cemented carbide cement concrete, crude cement concrete, etc., depending on the material or construction method of cement concrete used for the surface layer 160, but all of them are included in the scope of cement concrete pavement.

On the other hand, the resin-based packaging is a package formed by using a material containing the epoxy layer, MMA (Methyl Methacrylate) resin, latex (latex) resin, etc. as a main component of the surface layer 160 is mixed with cement or the like to form the surface layer 160 It may also be considered to be included in the scope of cement concrete pavement if it is mixed with cement.

In the conventional cross-linking pavement, the waterproof layer 120 is constructed to prevent the penetration of rainwater into the structure 100, and the adhesion between the waterproof layer 120 and the structure 100, and the waterproof layer 120 and the base layer 140 is improved. In order to increase the adhesive layer (110, 130) is constructed.

However, in the present invention, by forming the modified sulfur binder layer 200 as shown in FIG. 2, it is possible to prevent intrusion of rainwater into the structure, as in the conventional waterproof layer 120.

In addition, it is possible to improve the waterproof performance and to increase the adhesive strength with the structure 100 and the base layer 140 even without including the separate adhesive layers (110, 130).

Particularly, in order to prevent penetration of rainwater into the structure 100, the waterproofing layer was formed by various methods such as a penetration system, a coating system, a sheet system, etc., but the waterproofing performance is greatly affected by external impact due to the specificity of the bridge. do.

However, by applying the modified sulfur binder used in the present invention to the structure 100, by the physical properties such as elasticity and waterproofness and chemical resistance of the modified sulfur binder to prevent penetration of the excellent to the structure 100, but also waterproof performance against external impacts, etc. There will be no effect.

In addition, since the modified sulfur binder used in the present invention has high adhesion to heterogeneous materials, it may be possible not to form separate adhesive layers 110 and 130 as shown in FIG. 1 between the structure 100 and the base layer 120. Will be.

Therefore, it is possible to further improve the performance of the waterproof and not be affected by external shocks, and also reduce the construction process.

Referring to Figures 3 and 4 the order in which the cross-section packaging method according to a preferred embodiment of the present invention will be described once again.

3 is a flowchart illustrating a conventional cross-linking packaging process, and FIG. 4 is a flowchart illustrating a cross-packing packaging process according to a preferred embodiment of the present invention.

As shown in FIG. 3, in the conventional cross-linking procedure, the adhesive layer 110 is constructed on the structure 100 (S300), and the waterproof layer 120 is constructed on the formed adhesive layer 110 (S302).

And after the adhesive layer 130 for increasing the adhesive strength with the base layer 140 to the waterproof layer 120 again (S304), the base layer 140 is constructed (S306).

Then, after performing a tack coat construction to increase the adhesion between the base layer 140 and the surface layer 160 (S308), the surface layer 160 is constructed (S310).

Meanwhile, as described above, when the surface layer 160 is constructed of cement concrete, resin, or the like instead of asphalt concrete, the tack coat construction of step 404 may not be included.

As shown in FIG. 4, the crosslinked pavement according to the preferred embodiment of the present invention has a high adhesive force even for heterogeneous materials, as described above. It may be possible to construct the structure 100 directly and to construct the base layer 140, the tack coating layer 150, and the surface layer 160.

In addition, in order to form a layer for increasing adhesion between the base layer 140 and the surface layer 160, for example, in the case of asphalt concrete pavement to construct a modified sulfur binder used in the present invention instead of the construction of the tack coating layer 150 It is also possible.

In addition, dipentene, vinyl toluene, styrene monomer, and dicyclo pentene may be added to DCPD alone or a mixture in which at least one of CPD, DCPD derivative, and CPD derivative is added to DCPD. At least one may be a mixture added.

And heterocyclic amines in the group consisting of pyridine, homopyridine, isomers of pyridine, isomers of pyridine, quinoline, isoquinoline, acridine and pyrrole It may be at least one selected.

It may also be a modified sulfur binder in which other substances are added to this modified sulfur binder.

Other materials are, for example, mineral powders, which can be various mineral fine powders such as natural aggregates, artificial aggregates, slag, coal ash, fly ash, silica fume, and the weight ratio is modified sulfur binder. It has a weight ratio of 20 to 50% with respect to 100% by weight and the particle diameter is preferably 70 microns (Sm), but is not limited thereto.

On the other hand, other materials added to the modified sulfur binder may be another modified sulfur binder having properties different from those of the modified sulfur binder.

FIG. 5 is a view schematically illustrating a process of generating another substance added to the modified sulfur binder when it is another modified sulfur binder having different physical properties from the above-described modified sulfur binder.

In FIG. 5, the modified sulfur binder 1 is a heterocyclic amine (hetero) based on 0.1 to 100% by weight of dicyclo pentadiene-based modifier and 100% by weight of sulfur as a sulfur and a sulfur modifier. Cyclic amine or alkylamine 0.01 to 200% by weight is melt mixed.

The modified sulfur binder 2 is a modified sulfur binder having a composition and physical properties different from those of the modified sulfur binder.

In the following description, for the sake of convenience, the modified sulfur binder developed and patented by the present applicant will be referred to as modified sulfur binder 1.

The modified sulfur binder 2 is a modified sulfur binder different from the modified sulfur binder developed and patented by the present applicant. For example, a modified oligomer and dicyclo pentadiene are produced by combining sulfur with sulfur. May be a modified sulfur binder.

Meanwhile, in the following description, modified sulfur binders other than modified sulfur binders developed and patented by the present applicant for convenience of description will be referred to as modified sulfur binders 2.

This modified sulfur binder 2 is generally melted and remelted at temperatures in excess of at least 100 ° C.

Meanwhile, other substances may be added to the modified sulfur binders 1 and 2.

In addition, both the modified sulfur binder 1 and the modified sulfur binder 2 may adjust physical properties according to the range of addition amount of the substance to be added.

Therefore, as shown in FIG. 5, the modified sulfur binder 1 and the modified sulfur binder 2 may be mixed to form a new modified sulfur binder (hereinafter, referred to as modified sulfur binder 3 for convenience of description) to adjust physical properties. Do.

In addition, it is also possible to add additional additives in addition to the modified sulfur binder 1 and the modified sulfur binder 2, and the blending ratio of the modified sulfur binder 1 and the modified sulfur binder 2 and the blending ratio of the other additives to be added may be variously set.

In addition, the control of the physical properties may vary depending on the mixing ratio of the modified sulfur binder 1 and the modified sulfur binder 2, and it is also possible to adjust the physical properties by further adding other additives in the mixing process.

The other additives in the mixing process may be various mineral powders such as natural aggregates, artificial aggregates, slag, coal ash, fly ash, for example, as mineral fine powders, but are not limited thereto.

Meanwhile, in FIG. 5, since the modified sulfur binder 2 is melted and remelted at a temperature exceeding 100 ° C., melt mixing is performed for mixing the modified sulfur binder 1 and the modified sulfur binder 2.

However, since the modified sulfur binder 1 has hydrophobicity which can be dissolved in water having a temperature of 100 ° C. or lower, the modified sulfur binder 1 is formed in the liquid phase by dissolving in water, and the modified sulfur binder 2 is formed in the liquid phase after melting. It is also possible to mix them together.

And the mixing ratio of the modified sulfur binder 1 and the modified sulfur binder 2 can be set in various ways, if the modified sulfur binder 1 and the modified sulfur binder 2 are combined together as described above is not limited.

On the other hand, such a modified sulfur binder may be formed of cement concrete or asphalt concrete and used to form road pavements or various structures.

First, with reference to Figures 6 and 7 looks at the production process of cement concrete that can be used in the bridge pavement according to an embodiment of the present invention.

Figure 6 of the present invention is a view schematically illustrating the process of generating concrete that can be used for the bridge pavement according to a preferred embodiment of the present invention, Figure 7 is used for a bridge pavement according to a preferred embodiment of the present invention It is a schematic diagram illustrating another production process of concrete that can be.

FIG. 6 illustrates a case in which a modified sulfur binder is first produced by using a liquid modified sulfur binder, and a modified sulfur cement concrete is produced. Illustrates the case of mixing with aggregate and water to produce modified sulfur cement concrete.

As described in the description of FIG. 5, the modified sulfur binder 1 may be prepared in a liquid phase by mixing the modified sulfur binder in a solid state with water.

However, the modified sulfur binder 3 may vary depending on the material to be added or the mixing ratio. However, the modified sulfur binder 3 is generally insoluble in water, and since the melting temperature exceeds 100 ° C., the modified sulfur binder may be formed through the melting process.

And cement concrete can be produced by mixing cement and aggregate with the modified sulfur binder formed in the liquid phase.

On the other hand, Figure 7 can be used to produce cement concrete by mixing the solid reformed sulfur binder in cement, aggregate and water when the modified sulfur binder used is a modified sulfur binder 1 in particular.

On the other hand, there is no limitation in the kind of cement included in the modified sulfur cement concrete used in the present invention.

In particular, in the case of cement cemented carbide or crude cement, for example, the curing time of the cement concrete to be constructed on the surface layer 160 may be rapidly reduced, which may be more advantageous for a bridge requiring rapid repair and reconstruction.

Furthermore, when the modified sulfur binder is used for the waterproofing of the structure 110, considering that the curing time of the modified sulfur binder is relatively quick compared to the curing time of general waterproofing materials, the modified sulfur binder is used as the waterproof layer 120. When the modified sulfur cement concrete produced using superhard cement or crude steel cement to the surface layer 160, it is possible to further shorten the construction period or time, but is not limited to this construction method.

In addition, it is also possible to form modified sulfur cement concrete by additionally including other materials in addition to the above-described modified sulfur binder, cement, and aggregate, and the additional materials may also include resins such as epoxy, MMA, and latex described above. As the mineral powder, it is also possible to further include various mineral fine powders such as natural aggregate, artificial aggregate, slag, coal ash, fly ash and silica fume.

When the asphalt mixture to be mixed with the aggregate is first produced using the modified sulfur binder, the modified sulfur binder 1 alone or the modified sulfur binder 3 generated by combining the modified sulfur binder 1 and the modified sulfur binder 2 is used as the modified sulfur binder. Prepare an asphalt mixture.

Except for adding the modified sulfur binder, the method for producing the asphalt mixture used in the present invention can be prepared by the same method as the conventional method for producing the asphalt mixture.

Of course, it would be possible to manufacture a method different from the conventional method of manufacturing the asphalt mixture, but by using the conventional method of manufacturing the asphalt mixture as it is, the production of the asphalt mixture with improved performance while using the conventional equipment and equipment for manufacturing the asphalt mixture as it is There may be an advantage that becomes possible.

And there is no limitation to the existing asphalt or asphalt mixture to be mixed in the production of the asphalt mixture, there is no limitation in the mixing ratio with the modified sulfur binder.

In particular, since both the asphalt and the modified sulfur binder are thermoplastic materials, it is possible to mix uniformly through the process of melt mixing.

However, the asphalt has a different melting temperature depending on the type, but generally has a viscosity of about 180cp at a temperature of about 160 ℃, it is also possible to adjust the physical properties of the modified sulfur binder itself to facilitate mixing.

In addition to the asphalt and the modified sulfur binder, it is also possible to add additional additives, and the mixing ratio of the asphalt and the modified sulfur binder and the mixing ratio of the other additives to be added may be variously set.

In addition, the control of the physical properties may vary depending on the mixing ratio of the asphalt and the modified sulfur binder, and it is also possible to adjust the physical properties by further adding other additives in the mixing process.

On the other hand, by mixing the modified sulfur binder, it is possible to further improve the waterproof, electrical insulation, adhesion and chemical stability of the conventional asphalt.

In particular, when the road pavement is carried out using the asphalt mixture according to the preferred embodiment of the present invention for road pavement, it is possible to further reduce noise and resistance when driving the vehicle due to the elasticity of the modified sulfur binder.

In addition, the waterproof property of the conventional asphalt is further increased, and the time for allowing the vehicle to pass immediately after road construction, which is one of the advantages of the asphalt pavement, is further shortened.

In addition, it increases the life of the asphalt pavement by increasing its resistance to plastic deformation, which is one of the biggest problems of conventional asphalt pavement.

Hereinafter, with reference to Figure 8 will be described a method for producing an asphalt mixture according to an embodiment of the present invention that can be used for pavement asphalt is the most widely used.
