In rainy days, the road surface will be scoured by rainwater and the surface layer will be covered by water film. Water will also enter the interior of asphalt pavement structure from the gap or other paths to damage it. Especially when vehicles pass through, the tires of vehicles will generate positive pressure on the water on the front asphalt pavement, which will push the water into the gap of road surface. After the tire passes, it will also generate negative pressure on the water of rear road surface, which will suck the water in the gap out. The dynamic water pressure formed by the process of such back-and-forth alternation continuously scours the surface layer of road surface, which eventually causes the peeling of road surface.
