摘要

Through conventional and unconventional tests, the influences of self-developed warm-mix agent on the performances of SBS modified asphalt are studied. The results show that the warm-mix agent has great influences on the ductility and aging quality changes of SBS modified aspha and the warm-mix agent can improve the asphalt rutting factor G*/sinδ and fatigue factor G* · sinδ. The mixing ratio of the warm-mix SBS modified asphalt mixture is designed based on GTM method and the pavement performance is compared and verified. The results show that: in terms of high temperature performance, the warm-mix asphalt mixture is superior to the corresponding hot-mix asphalt mixture; and in terms of low temperature performance and water stability, the former is equivalent to the latter.
