In this paper,the design of AC-20 asphalt mixture mix is studied.By analyzing the characteristics and influencing factors of recycled asphalt,as well as the key parameters such as the gradation and physical properties of the stone,a reasonable mix ratio design method was determined.Under laboratory conditions,the properties of the mixture under different asphalt contents were compared by Marshall test and related test methods.The results show that moderate control of asphalt addition can significantly improve the stability,shear strength and durability of the mixture.
