[0002] During long-term use, asphalt pavement will be subjected to vehicle rolling and environmental factors, and cracks will appear on its surface. If it is not repaired in time, the accumulated water on the road will enter the base layer through the gaps. The water may carry away the soil layer of the roadbed, or it may form mud with the soil layer and be squeezed out when vehicles roll over the gaps in the road surface, causing damage to the road surface and shortening the service life of the road surface.
