为了确定用于沥青混合料高温性能设计的最优试验方法和评价指标，分别采用动态模量试验、间接拉伸强度试验、车辙试验和单轴重复荷载试验对9种沥青混合料的抗车辙性能进行测试，通过统计学方法对比分析了不同试验方法的合理性。试验结果表明：动态模量试验和高温间接拉伸强度试验不能准确地评价混合料的抗车辙性能；车辙试验仅适用于区分不同新拌沥青混合料抗车辙性能的优劣，是否适用于评价再生混合料尚存疑问；重复荷载试验具有更好的区分度和合理性，并可得到材料的基本力学参数；将基于重复荷载试验的流变次数指数作为抗车辙性能评价指标更为准确；在评价新拌沥青混合料时车辙试验和重复荷载试验结果具有良好的相关性，但是该关系并不能拓展到再生混合料中。

The dynamic modulus test,indirect tensile strength test,wheel tracking test and uniaxial repeated load test were respectively used to evaluate the anti-rutting performance of nine types of as-phalt mixtures to determine the optimum testing method and indicators of high temperature perform-ance for asphalt mix design.The reasonability of these tests was compared by statistical methods. The results show that the anti-rutting performance of asphalt mixtures cannot be accurately evaluated by the dynamic modulus test and indirect tensile test at the high temperature.The wheel tracking test can only be used to identify the anti-rutting performance for new hot mix asphalt mixtures and its fea-sibility for reclaimed asphalt mixtures is questionable.The repeated load test has better differentiation and reasonability,and the fundamental mechanical parameters of materials can be obtained.The flow number index obtained from the repeated load test is a rational indicator to the anti-rutting perform-ance.The good correlation between the wheel tracking test and repeated load test is observed in new hot mix asphalt mixtures;however this correlation cannot be extended to reclaimed asphalt mixtures.
