沥青路面渗水试验检测与防治对策

Permeability Test of Asphalt Pavement and countermeasures

沥青路面渗水的原因主要包括水力冲刷、置换作用等。工程运营前要严格按照规范要求进行渗水试验,计算并整理渗水系数。同时还要合理选择面层结构、重视施工质量控制、提高沥青与集料的结合性能、改善排水设施,对渗水路面也要及时采取措施处理。从而实现对渗水现象的有效预防,确保沥青路面工程质量。

The reasons of asphalt pavement seepage mainly include the hydraulic erosion and replacement effect.Before the engineering operations,asphalt pavement should be strictly tested in accordance with the requirements of the specification of Permeability test.It is necessary to select the structure of the surface,pay attention to the construction quality control,improve the combination of asphalt and aggregate,improve the drainage facilities,as well as the seepage pavement,so as to realize the effective prevention of the seepage phenomenon and ensure the quality of asphalt pavement engineering.
