摘　　要：沥青混合料抗剪性能不足是路面车辙病害的主要原因,选择合理的沥青混合料抗剪性能试验方法及评价指标尤为重要,选择三轴、同轴剪切和单轴贯入试验,进行沥青混合料抗剪性能检测方法比较,结果表明三种试验方法得到的试验结果规律相同,评价结果相似,均可作为沥青混合料抗剪性能的试验方法,在三轴试验不具备条件情况下,同轴剪切与单轴贯入试验方法也可用来检测沥青混合料的抗剪性能。The lack of anti-shear properties of asphalt pavement leading to early diseases such as rutting, the selection of shear test methods and performance evaluation is particularly important. Coaxial shear,triaxial shear tests and the uniaxial penetration test are used to compare the performance of these asphalt mixture shear test methods in this paper. It can be found that the raw of coaxial shear, triaxial shear tests and the uniaxial penetration test results is uniform, evaluation results are similar, and all these tests can be used as the performance of asphalt mixture shear test method. In no condition to conduct the triaxial shear test, the coaxial shear and uniaxial penetration test method can also be used to measure the anti - shear properties of asphalt mixtures.
