摘　　要：以新疆地区常用的四种沥青为例,运用动态剪切流变试验分析沥青短期老化前后车辙因子随温度的变化规律,用以评价沥青的高温性能及疲劳性能。试验结果表明:SBS(I-C)改性沥青的高温性能优于其他品种沥青,但它的疲劳性能需关注,橡胶沥青的高温性能及疲劳性能均较优。Four kinds of common asphalt used in Xinjiang area were taken as samples. Dynamic shear rheometer test were used to analyze the changing law of rutting factor along with the temperature change in short term aging. This way can be used to evaluate the high temperature performance and fatigue property of asphalt. It was showed that the high temperature performance of SBS （ I - C） modified asphalt was better than other varieties. But its fatigue performance needed to be concerned. The high temperature performance and fa- tigue performance of rubber asphalt were excellent.
