Since the asphalt pavement with low cost, low noise, driving comfort, easy maintenance and other advantages, in recent years, the asphalt pavement has been widely promoted and applied in highway construction. Cracks as one of the common diseases of asphalt pavement has great danger to the pavements, especially in winter and spring.
After cracks appeared , rainwater infiltration along the crack to the grass roots, if not promptly take measures to dispose , repeated traffic load, cracks in the disease state of rapid expansion causing further damage to asphalt pavement and grass-roots, reducing its performance. Therefore, in order to improve pavement quality and reduce the development of diseases,we must take early measures to prevent further damage after asphalt pavement cracks appear.
