摘要：

To scientifically select and evaluate ultra-thin wearing course asphalt mixture, three types of asphalt mixture, SMA-10, UTAC-10 and NovaChip Type-C were selected to study the performance evaluation indicator. The low temperature performance of mixture was evaluated by use of thermal stress rest rained specimen test, and the surface performance was evaluated by permeable coefficient test and anti-slide performance test. A kind of indoor abrasion test was designed to evaluate the skid resistance attenuation property of asphalt mixture, and a set of dispersion tests under three conditions was designed combining with freeze-thaw splitting test to evaluate water damage resistance performance of asphalt mixture. The results show that the frozen broken temperature and frozen broken strength can effectively evaluate the low temperature performance of ultra-thin wearing course asphalt mixture. It is scientific to use initial value of BPN and sliding attenuation degree to evaluate skid resistance performance of ultra-thin wearing course. Freeze-thaw splitting strength ratio and freeze-thaw splitting strength should be combined to evaluate resistance water damage performance.
