摘要：
Fine aggregates are sensitive parts to skeleton structure of mixture and decrease rutting resistance of asphalt mixtures. In order to evaluate the high temperature performance of mixtures with different fine aggregate (2.36mm and 1.18mm) content, 16 gradations were investigated. Flow number test and rutting test was conducted to evaluate anti-rutting performance of mixtures. Then, interference coefficient was put forward to analyze interference rule of high temperature performance. The results show that high temperature performance was improved with the increasing size of nominal maximum aggregate size; the interference effects of fine aggregate ( 2.36mm and 1.18 mm) is inversely proportional to nominal maximum aggregate size.
