摘　　要：在沥青混凝土中添加导热相材料—石墨可有效提高沥青材料的热传导性能。该文在普通沥青混凝土中掺入石墨设计出了传导沥青混凝土路面,并通过在传导沥青混凝土路面中埋入换热管道达到冬季融雪化冰的目的。全文从室外大板试验到数值分析对比,说明了传导沥青混凝土路面融雪的适用性及可行性。To add the graphite into asphalt mixture can improve the thermal conductive performance of asphalt concrete effectively.In the study,the conductive asphalt concrete with graphite is designed.And the heat exchange tubes are interred in the asphalt concrete in order to melt the ice and snow in the road.The outdoor experiment of lager asphalt slab is done,and at the same time the simulating calculation is analysed.Ultimately,the research result showed that the conductive asphalt concrete can be used to melting ice and snow effectively.
