[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. After a period of use, asphalt pavement will be eroded by vehicles and rain, and numerous cracks will appear on the surface of the asphalt pavement. If the cracks are not repaired in time, the cracks will further spread under the action of vehicle loads. In addition, when rainwater enters in winter, the rainwater freezes, which will aggravate the evolution of the cracks, further deepen the level of damage to the road surface, and seriously affect the service life of the road surface. Therefore, when cracks appear in the asphalt pavement, it is necessary to repair the cracks in the asphalt pavement in time to extend the service life of the road surface.
