The water damage was an important factor causing asphalt pavement damaget,he current use of asphalt pavement measured seepage water seepage coefficient method has been unable to meet the requirements of rapid development of highways.

主要针对目前渗水仪定点检测沥青路面渗水系数方法的效率低、代表性差的不足,首先成型不同连通空隙率的沥青混凝土板状试件,经过一定时间的饱水,利用红外测温技术检测不同连通空隙率沥青混凝土试件表面温度差异度,从而提出利用红外差热技术快速、连续检测评价沥青混合料渗水性的方法。
