Description

Multi-functional asphalt joint reinforcement installation device {Moving hopper system of asphalt joint reinforcement}

The present invention relates to a multifunctional asphalt joint reinforcement laying apparatus, and more particularly, to a multifunctional asphalt joint reinforcement laying apparatus capable of applying a liquid reinforcement or attaching a tape-type reinforcement to the boundary or cracked portions of asphalt.

In general asphalt roads, cracks in which a part of the road surface is partially split occurs due to various factors such as repeated expansion and bumps, shocks transmitted by vehicles, irregularity in loads and stresses, aging or subsidence. According to the geometrical shape of such asphalt cracks, longitudinal cracks, transverse cracks, cracks due to construction joints, cracks such as turtles, and block cracks occur, and sliding cracks, shrinkage cracks, and reflection cracks occur depending on the cause of occurrence.

As such, the process of cracking the asphalt road is caused by a number of reasons, and it is determined gradually downward from the surface, and water infiltrate is generated by rainwater and water as the cracked part, and the foundation part of the road is softened by the infiltrate. The paved road loses the strength that the road foundation supported. In asphalt pavements softened by infiltrating water due to the influence of the vehicle load downward, the foundation is compressed and repeated, increasing fatigue. The point where the softened asphalt foundation and the surface of the road meet becomes a new crack point, and as this action is repeated, the crack progresses gradually and cracks.

A new crack occurs even in the part where there was no one, destroying the pavement.

Rainwater or foreign matter enters through the cracks generated in this way, causing the cracks to become larger, and if left unattended for a long time, it leads to road damage, which may not only interfere with vehicle traffic, but also cause safety accidents. there was.

Asphalt pavement crack repair method and apparatus using a conventional infrared heating device to solve the above problems include a base, a duct installed on the base, a heating plate installed on the bottom of the duct and heating the crack groove of the asphalt, and the base A heating part installed in the duct and connected to the duct to heat the heating plate under the duct, and the heating part installed in the base and connected to the heating part so that the injected sealant melts, and when the base moves along the crack groove, sealant injection to inject the sealant into the crack groove. Consists of wealth. Therefore, since the crack groove of asphalt is heated by a heating unit to dry it, and the sealant is injected into the heated crack groove, the asphalt crack groove heating and sealant injection operation can be continuously performed with one device, thereby improving workability.

However, the conventional asphalt pavement crack repair device heats the cracks of the asphalt and then injects sealant into the heated cracks.In this process, if the injection amount of the sealant must be varied according to the size and width of the cracked area, this is satisfied. There was a problem that could not be done.

In addition, since the conventional asphalt pavement crack repair device only provides a technology in which only liquid sealant is injected into the crack area, it is difficult to maximize the cohesive force of the crack area.In particular, it is difficult to maximize the cohesion of the crack area. There was a problem in that the adhesion was reduced and additional cracks or fall off at the cracked area.
