摘　　要：水损害是沥青路面病害的一种。大量资料显示,路面结构内下渗的自由水是路面损坏的直接原因。水损害不仅会引发坑槽、车辙等严重病害,还会缩短路面使用年限,给车辆行驶安全带来威胁。为提高沥青路面结构抗水损能力,从内部排水和边缘排水方面进行分析与探讨,以期提高路面结构性能。Water damage is one of the diseases in asphalt pavement,and according to a large amount of data,the direct cause of pavement damage is the free water seepage inside the pavement structure.Water damage not only causes serious diseases such as potholes and ruts,but also shortens the service life of the road surface,posing a threat to vehicle driving safety.In order to improve the water resistance of asphalt pavement structures,this article analyzes and explores the internal drainage and edge drainage aspects,in order to improve the performance of pavement structures.
