水损坏已经成为南方多雨地区的最主要病害之一。引起水损坏的原因为多方面,既有沥青面层的施工质量、原材料以及车辆超载等原因,也有路面结构防排水系统设计的不完善。介绍美国AASHTO 2002路面结构层防排水系统设计理念,以供同行共同学习、探讨。

Water damage is one of main disease in south rainy region. Apparently, it has many aspects to cause water damage which includes construction quality of asphalt pavement; raw and processed materials; overloading of cars and faultiness of design on drainage system of pavement structure. This paper introduces design theory of pavement structure layers drainage system in AASHTO 2002 guidelines, it affords opportunity to study and discuss.
