摘　　要：为验证导电沥青混凝土的路用性能,并进一步探究其功能特性,进行水稳性能、抗裂性能、强度性能试验,对比分析普通沥青混凝土、石墨导电沥青混凝土和复合导电沥青混凝土的路用性,并分析导电沥青混凝土的力-电机敏特性。结果表明:石墨对沥青混凝土的路用性能均有不良影响,而碳纤维可提高沥青混凝土的路用性能,石墨和碳纤维复合使用能满足规范的要求;碳纤维导电沥青混凝土具有显著的力-电机敏特性。In order to verify the road performance of conductive asphalt concrete and further explore its features,water stability,crack resistance and strength performance tests are conducted.The road performance of ordinary asphalt concrete,graphite conductive asphalt and composite conductive asphalt concrete are compared,and the relationship between resistance and tensile displacement is analyzed.The results show that:graphite has an adverse effect on the road performance of asphalt concrete,and carbon fiber can improve the road performance of asphalt concrete.The compound use of graphite and carbon fiber can meet the requirements of the specification,and carbon fiber conductive asphalt concrete has strong force-resistance sensitivity characteristics.
