Abstract: The main factors that affect the durability of asphalt concrete pavement are the quality of rutting, cracks and semi-rigid base. The factors such as large traffic volume, high air temperature and improper composition of pavement materials lead to the formation of rutting. Due to different reasons, the cracks are divided into fatigue crack, temperature crack and reflection crack. The strength and erosion resistance of semirigid material and the quality of construction will affect the quality of semi-rigid base. It is found that the reasonable design of pavement structure and mixture ratio, and the correct construction methods and maintenance methods can improve the quality of the base to improve the durability of asphalt pavement.
