Asphalt pavement cracks are the most common problem under heavy-duty traffic. Asphalt pavement is one of the early major diseases that is most likely to cause other diseases. Asphalt pavement cracks not only destroy the continuity, integrity and aesthetics of the pavement, but also seriously affect the service life of the pavement. If effective measures are not taken in time for preventive maintenance and maintenance, it will cause damage to a larger area of the road, and even cause serious traffic accidents.
