摘　　要：通过分析路面水损坏的实际情况及国内外研究现状,可知进入路面结构内的水是造成或加速路面损坏的主要原因,设置路面结构内部排水系统有利于防止病害产生,延长路面使用寿命.本文从需要及经济两方面提出了路面内部排水系统的设置条件和设计要求,阐述了目前国内外应用的路面内部排水系统的各种形式,详细论述了开级配粒料、结合料稳定粒料及多孔混凝土排水基层,边缘集水沟管和隔离层等内部排水系统的材料组成,就路面内部排水系统的施工及注意事项予以概要介绍.By analyzing the water damage of pavement, it is known that water coming into the pavement is the main factor causing or accelerating pavement damage, and setting the pavement subsurface drainage system can prevent pavement damage and prolong the pavement service life. From the aspects of requirement and economy, the setting condition and design requirement of subsurffice drainage system was put forward in the paper. Every type of subsurface drainage system used at present was presented and the material composition of permeable base, such as open-graded aggregate, bindertreated aggregate and porous concrete, edge collecting gutter and pipe, and insulating layer etc. was developed particularly. At last, the construction and some events of subsurface drainage system were introduced generally.
