摘要：沥青混合料的车辙性能评价指标的选取是混合料设计的关键技术之一，本文在分析车辙的形成机理以及现有车辙性能评价指标缺陷的基础上,通过大量的不同温度、不同压力、不同厚度的车辙试验、抗剪试验以及车辙试验剪应力的计算，然后通过曲线拟合法分析了抗剪强度对车辙性能的影响，提出了将抗剪强度作为车辙性能新评价指标的建议，对丰富沥青混合料的车辙性能检测、评价具有重要意义。

The Influence of Shear Resistance on Rutting Ability of Asphalt Mixture

LU Zheng-lan  SUN Li-jun

Abstract: The evaluation indicator of asphalt mixture rutting resistance is one of the key factors in asphalt mixture design. Based on analysis of rut formation and the shortness of evaluation indicators of rutting ability at present, through a lot of rutting tests in different temperature and different stress and different depths, this paper puts forward a new evaluation indicator of rutting resistance. It is very important to test and indicate rutting resistance of asphalt mixture.
