Technical Field
The application relates to the technical field of road construction, in particular to a road crack repairing device and a repairing method.
Background
At present, pavement layers of structures such as roads, basketball courts, parking lots and the like are easy to crack under the comprehensive action of conditions such as climate, load, material self factors and the like. In cold areas or areas with large temperature difference between day and night, even if roads are newly built, the pavement is easy to shrink and crack within 1-2 years of use. In China, a semi-rigid base asphalt pavement is the most commonly applied road structure type, and besides thermal shrinkage cracking, reflective crack diseases caused by thermal shrinkage and dry shrinkage characteristics of the semi-rigid base are particularly common. The surface cracking will induce more severe structural damage under the action of factors such as water temperature, driving load, etc. in addition to affecting road aesthetics, integrity and driving comfort. For example, after the asphalt pavement cracks, rainwater can penetrate into the pavement structure along the cracks, so that asphalt and stone are peeled off, the rigidity of the base material is reduced, the pavement is damaged by loosening, pot holes, mud pumping, sinking and the like, and the service life of the pavement is shortened. If the crack is not repaired in time or the means is improper, the crack can be rapidly expanded, and the service life attenuation is accelerated, so that the proper crack repairing measures are adopted, and the method has practical significance for guaranteeing the integrity of the road structure and prolonging the service life of the road.
