The present invention relates to a recyclable road pavement structure that is constructed in an emergency stop region of Ascon pavement and a construction method of the road pavement structure.

As is well known, asphalt or concrete is often used for pavement.

Ascon is a mixture of asphalt and coarse aggregates, fine aggregates, and pavement fillers (limestone powder, cement, etc.) at room temperature or at room temperature, and is widely used for road paving and parking lot paving. At this time, the asphalt concrete pavement is divided into a hearth / selective layer / auxiliary layer / base layer / surface layer. The base layer and the surface layer are formed by paving the asphalt concrete having different particle sizes of the mixed aggregate. However, the asphalt contained in ascon is sensitive to changes in temperature, and ascon pavement is a plastic deformation in summer, which causes severe bends on the surface, which can interfere with car traffic. Cracks can also shorten the surface and substrate lifespans significantly. In particular, plastic deformation of ascon is caused not only by the change in temperature but also by the load transmitted from the vehicle (hereinafter referred to as a traffic load). FIG. 1 is for explaining a form in which a traffic load is transmitted to an existing ascon pavement. It is a block diagram.

Referring to FIG. 1, the asphalt road pavement 100 has a traffic load transmitted from a wheel w of the vehicle in a radial form, and the loads are transferred to the surface layer 100a, the base layer 100b, and the auxiliary base layer 100c. It diffuses in order of the selection layer and the hearth (100d). In other words, the surface layer 100a of the asphalt road pavement 100, that is, the surface layer 100a formed by paving the asphalt, supports only a portion of the traffic load and transfers the portion to the substrate.

Accordingly, the plastic layer is easily generated due to the traffic load transmitted in the diffusion form of the surface layer 100a of the asphalt concrete pavement 100, and in particular, of the vehicle emergency stop region 110 in which the traffic load is doubled as the vehicle stops suddenly. In the asphalt road pavement 100, Figure 2 is a plan view for explaining the plastic deformation appearing near the crosswalk as an example of the vehicle sudden stop area on the asphalt road.

Referring to FIG. 2, the pedestrian crossing 200 is a part of a roadway that a person crosses on the asphalt road pavement 100. The stop line 210 of the vehicle is displayed on the front roadway of the crosswalk 200, and the crosswalk notice 220, which is indicated by diamonds, is drawn on the roadway 50 meters ahead of the stopline 210, so that the driver Notified that there is a crosswalk 200 ahead. Therefore, all vehicles have to temporarily pause at the front of the crosswalk 200, that is, at the stop line 210 when the pedestrian is passing through the crosswalk 200, so that the speed of the vehicle is rapidly reduced. As the traffic load is doubled, the roadway to the front of the crosswalk 200, for example, up to 50m ahead of the crosswalk 200, may be classified as a vehicle sudden stop region 110 in which plastic deformation of the asphalt concrete surface occurs.

Therefore, the small deformed asphalt road pavement 100 performs the asphalt concrete repair work (partial repair work) for resurfacing after crushing the surface layer 100a or the surface layer 100a and the base layer 100b. Ascon pavement 100 of the stop area 110, as the plastic deformation is frequently performed a frequent sofa repair work.

However, the existing asphalt road pavement 100, in particular, the asphalt road pavement 100 of the vehicle stop area 110 is carried out in a state that partially blocked the traffic of the road during the sofa maintenance work cause of traffic jam Becomes In addition, when crushing a part that needs repair, that is, a part where plastic deformation has occurred, by using a crusher, noise is generated as well as dust, which causes noise damage to neighboring houses and shops, and repacks Ascon. Emulsions used to do so remain on the road, causing environmental pollution. In addition, the underground buried display displayed on the asphalt concrete pavement 100 of the vehicle sudden stop area 110 is removed during the sofa repair work as described above, so if the underground buried display is not displayed thereafter, the place where the underground buried is buried. There is a considerable difficulty involved in the maintenance of underground burial.

Therefore, in recent years, ascon has been proposed to further include a modifier such as SBS, SIS or LDPE in order to improve the problems of the plastic deformation. Such modifiers are intended to prevent plastic deformation in summer and to prevent winter cracking by changing the physical properties of asphalt, but the effects of preventing plastic deformation and cracking according to the change of asphalt physical properties have not been systematically proved. It has also not been proven that changes can prevent plastic deformation on traffic loads.

On the other hand, the concrete pavement is the surface layer or the surface layer and the base layer by the construction of the concrete slab, compared with the above-mentioned asphalt concrete pavement has the advantage of high durability and excellent durability. In addition, the transmission form of the traffic load on the concrete pavement is a concrete slab (300a) is a type that supports the traffic load as shown in Figure 3 (constitution diagram for explaining the form in which the traffic load is transmitted to the concrete pavement) Therefore, the traffic load is transmitted in a straight line. Accordingly, the concrete pavement 300 is to minimize the plastic deformation appear in the asphalt concrete pavement.

However, the concrete pavement 300 has a disadvantage in that the construction speed is lower than the asphalt road pavement, the noise due to the road surface, the maintenance cost is large. In particular, when repairing the sofa of the concrete pavement 300, a long time is required for the curing process after placing concrete, so that a rapid repair work cannot be performed, and the traffic must be blocked for a long time, thereby increasing traffic jams. There is this.

Therefore, the concrete pavement 300 is applied only to the highway to date, and other national roads and local roads are constructed as the asphalt road pavement 100.

Thus, the present invention was devised to solve the general problems appearing in the vehicle sudden stop area of the asphalt road pavement, especially ascon pavement is frequent due to traffic load,

The technical problem to be achieved by the present invention is to prevent plastic deformation as well as to prevent slipping of the vehicle, and by installing a recyclable installation block in a vehicle sudden stop area where plastic deformation occurs frequently according to plastic deformation The present invention provides a recyclable road pavement structure and a construction method of the road pavement structure, which are installed in a vehicle sudden stop area of the Ascon pavement, which can solve the problem of the asphalt road.

Another technical problem to be achieved by the present invention is to simplify the construction work by assembling / disassembling the installation block on the installation space portion provided in the vehicle emergency stop area, as well as can be easily performed sofa repair work, Recyclable road pavement structure that is constructed in the emergency stop area of Ascon pavement to minimize the damage of the underground buried markings by marking underground buried on the installation space. To provide a construction method of the road paving structure.

Another technical problem to be achieved by the present invention is to perform the sofa repair work in a short time according to the construction of the installation block in the assembly / disassembly method, minimizing the traffic congestion caused by blocking traffic of the vehicle and at the time of sofa repair work The present invention provides a recyclable road pavement structure and a construction method of the road pavement structure, which are constructed in an emergency stop area of the Ascon pavement to minimize noise and environmental pollution.
