Asphalt concrete cracking may be fatigue cracks caused by repeated traffic loads, or temperature cracks caused by rapid fluctuations in the pavement temperature field, or a combination of the two. In order to select the optimal treatment strategy for cracked asphalt pavements and determine the extent of cracks, it is necessary to first detect the cracks, such as detecting the width, shape or depth of the cracks, and then select the optimal treatment strategy for the cracked asphalt pavement based on the cracking conditions.
