| Abstract: | Fatigue performance of the modified bitumen SMA is evaluated and analyzed through test using four crooked fatigue testing equipment. Comparing with high temperature and low temperature, un-aged and long-term aged fatigue test, fatigue curve, fatigue equation and fatigue life forecast model are obtained. The results indicate that the modified SMA has excellent durable anti-fatigue performance. |
