Generally, roads running on runways or vehicles that require durability and flatness are generally made up of heated asphalt pavement (also referred to as "asphalt pavement"), and depending on the installation site, .

Asphalt pavement can also be classified into asphalt pavement, shrinkage, expansion, artificially sprayed chloride, ultraviolet ray and asphalt binder (asphalt composition) aging due to traffic volume, passing load, soil behavior, rainwater, moisture, .

In addition, asphalt or asphalt mixtures are undergoing long-term aging (LTA) during short-term aging (STA) and long-term use during manufacture, transportation, and construction.

These short-term aging or long-term aging show the deformation of the asphalt pavement during the process of volatilization where a small amount of volatile components evaporate during the manufacture, installation and use of the product, thereby shortening the lifetime of the asphalt pavement.

In addition, the cause of the aging of the asphalt which is used in common is that the aging of the asphalt binder increases the hardening and brittleness of the asphalt binder over time, and the durability of the asphalt binder deteriorates. As a result, .

That is, the plastic deformation of asphalt occurs in a state where the fluidity of the binder exists in the initial stage of construction (approximately 2 to 3 years), and the crack occurs in the medium term (approximately 5 to 6 years) in which the fluidity of the binder is lost.

In this process, damage and breakage such as plastic deformation, portholes, surface cracks, reflection cracks, level differences, subsidence, and frozen waves appear in the asphalt pavement, and rainwater and foreign matter penetrate into the pavement and further durability and flatness , The usability is deteriorated, and there is a problem that the efficiency of the maintenance which lowers the lifetime of the asphalt paved road and the repacking cycle is raised.

The method includes a step of forming an asphalt emulsion coating layer on an asperity coating surface on a construction surface, a step of moving a vehicle on the asphalt emulsion coating layer Wherein the glass fiber is formed so as to form a lattice shape. The glass fiber is divided into first and second glass fibers and then crossed with the carbon fiber. Wherein the lattice network is formed by alternately repeating intersections between the upper and lower portions of the glass fiber and the glass fiber, and the lattice net in which the glass fiber is wrapped around the glass fiber, and the lattice network is impregnated with the impregnation machine containing the asphalt emulsion A resin film layer formed on the lower side of the lattice network, A carbopallite fiber reinforcing member formed of a non-slip layer formed on a coating layer coated on the carbon fiber reinforcing member is heated and burned to remove the resin film layer and disposed on a surface on which the asphalt emulsion coating is formed. And a step of forming an asphalt pavement layer on the upper side of the carbobalt fiber reinforcing material so that the asphalt is packed to a thickness of 2 to 5 cm.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The asphalt pavement structure of the present invention includes an asphalt adhesive 10, a reinforcing fiber grid 20, and an ascon 30 on a base surface, as shown in Fig.

The substrate may include an asphalt substrate, a concrete substrate or a steel substrate, whichever of the substrates forms the asphalt pavement.

The asphalt adhesive 10 is a means for improving the waterproof function of the base surface and the adhesive strength of the reinforcing fiber grid 20. [

The asphalt adhesive 10 comprises 40 to 65 parts by weight of petroleum-based asphalt, 7 to 10 parts by weight of urethane rubber, 15 to 20 parts by weight of a reactive inorganic filler, 7 to 10 parts by weight of an absorbent polymer resin, 5 to 10 parts by weight A minor petroleum resin and 1 to 10 parts by weight of an isocyanate-based compound.

The petroleum-based asphalt is a composition which improves the adhesive force between the base surface and the ascon 30 and the physical properties such as heat resistance, elasticity and water resistance. When the amount is less than 40 parts by weight, the physical properties described above can not be secured. If it is more than the above amount, the physical properties are maintained but the manufacturing cost is increased due to the addition of the material.

When the amount of the urethane rubber is less than 7 parts by weight, the elasticity of the urethane rubber can not be secured. When the amount of the urethane rubber is more than 10 parts by weight, the elasticity of the urethane rubber is maintained. However, There is a problem that the manufacturing cost is increased.

When the amount of the reactive inorganic filler is less than 15 parts by weight, the above-mentioned physical properties can not be secured. When the amount is less than 20 parts by weight, the physical properties are maintained. However, There is a problem in that the manufacturing cost increases due to the addition of For example, the reactive inorganic filler is silicon carbide (SiC), aluminum nitride (AIN), zinc oxide (ZnO), chevron nitride (BN) and aluminum oxide (Al ₂ O ₃₎ any one or a selected one formed of at least one of . Of course, the present invention is not limited thereto, and any material or composition that can improve physical properties can be used.

The water absorbent polymer resin is a composition for enhancing physical properties such as permeability through surface modification treatment. When the amount is less than 7 parts by weight, the surface modification effect can not be obtained. When the amount is more than 10 parts by weight, water is retained. There is a problem that is raised.

The petroleum resin is a light yellow or blackish brown thermoplastic resin having a molecular weight of 2000 or less and obtained by polymerizing an unsaturated hydrocarbon present in high temperature pyrolysis such as naphtha as a raw material with an acid catalyst. In this case, if the amount is less than 5 parts by weight, the required viscosity can not be secured. If the amount is more than 10 parts by weight, the workability is deteriorated due to excessive viscosity.

The isocyanate compound functions as a crosslinking agent between the compositions. If the amount is less than 1 part by weight, the function of the crosslinking agent is not sufficiently exhibited. If the amount exceeds 10 parts by weight, the function of the crosslinking agent is maintained, Thereby deteriorating the physical properties. Examples of the isocyanate compound include 4,4'-methylenediphenyl diisocyanate (MDI), p-phenylene diisocyanate (PPDI), 1,6-hexamethylene (HDI), 1,5-naphthalene diisocyanate (NDI), isoporon diisocyanate (IPDI), toluene diisocyanate TDI) or one or more selected ones.
