摘　　要：选取碎石型和圆型两种类型陶粒,对其主要性能指标进行测试,然后对以不同质量替代率替代玄武岩集料的碎石型陶粒和圆型陶粒轻质环氧沥青混合料使用性能进行了研究,通过强度、抗车辙性能、水稳定性试验,确定了陶粒种类和替代率对轻质环氧沥青混合料性能的影响程度,推荐替代率为70%(质量分数)的圆型陶粒轻质环氧沥青混合料作为超长跨径桥梁和特殊结构桥梁(如开启桥等)钢桥面铺装的材料.Two kinds of lightweight aggregates,granulated lightweight aggregate（GLWA） and circular lightweight aggregate（CLWA）,were studied.At first,the performance of GLWA and CLWA were tested. Then strength performance,rutting resistance,moisture susceptibility of epoxy asphalt mixture with different use level of GLWA and CLWA were studied.The influence of the kind and the use level of lightweight aggregate on the performance of lightweight epoxy asphalt mixture was investigated.The result shows that the mixture with 70%（by mass） of CLWA incorporated is found to be the most suitable mixture for deck paving of long span or special construction bridge,such as moveable bridge.
