摘　　要：选取国内研发的7610型环氧沥青为结合料,以最大公称粒径为16 mm的玄武岩为集料,利用单轴贯入试验对不同级配组成的环氧沥青混合料抗剪性能进行了试验研究,并采用正交试验法对不同沥青材料混合料的抗剪性能进行了对比.结果表明,环氧沥青混合料的抗剪性能远优于一般的沥青混合料,对其影响程度较大的因素主要是油石比和4.75 mm粒径通过率.The 7610 type domestic epoxy asphalt was selected as the binder and the basalt with a nominal maximum aggregate size of 16mm was selected as the aggregate,the epoxy asphalt mixtures with different gradations were formed using the gyratory compactor and tested through uniaxial penetration test.The shearing behaviors of asphalt mixture with different binders were compared according to the orthogonal test.The results show that the shearing performance of the thermosetting epoxy asphalt mixture is better than that of the normal asphalt mixtures,the asphalt content and the passing rate to 4.75mm particle size are the major influencing factors.
