摘　　要：介绍和对比了三种沥青混合料高温稳定性能的评价方法。车辙试验应用广泛,其不足也比较明显;旋转压实剪切试验机(GTM)试验和单轴贯入试验能够简便快速地检测沥青混合料剪切性能,两者具有较高的相关性,可以作为评价高温稳定性能的有效手段。Three evaluation methods of asphalt mixture high temperature stability performance have been introduced and compared. Rutting test has been widely used, its shortcomings is also obvious ; Gyratory testing machine （GTM） and u- niaxial penetration test could easily and fast detect shear performance. There＇s a good linear relationship between the two test results. Both of them are effective means to evaluate high temperature stability performance of asphalt mixture.
