With the development of China's highway construction , traffic volume and traffic load increases, the durability of asphalt pavement to be tested . Theoretically , SMA pavement has excellent durability , but in recent years there have application in many problems. In this paper, the durability of SMA mixture influencing factors analysis, for better Mix Design of SMA to provide theoretical guidance . In this study, different types of powder -binder ratio and filler mastic asphalt before and after aging penetration, softening point and ductility test comparison and analysis of the powder -binder ratio and filler types on SMA mixture anti-aging properties ; using the immersion Marshall test and freeze-thaw splitting test , fatigue test , in-depth study of various factors on the stability of mixtures of water and fatigue properties of the degree of influence , such as the 4.75mm sieve passing rate , slag dosage, type and amount of asphalt and porosity . Test results showed that SMA mixture of various factors on the stability and fatigue properties of the water in varying degrees. Finally, the test road were analyzed .
