摘　　要：排水性沥青路面(OGFC)是一种新型的路面结构,具有排水、降噪和抗滑功能。文章介绍了OGFC配合比设计、施工中应注意的问题,并对OGFC使用的高粘度改性沥青和SMA使用的改性沥青的成本进行了经济对比分析,指出,OGFC面层不但具有良好的排水、降噪功能,而且造价低于SMA路面。The porous asphalt pavement with open - graded friction course （ OGFC ） is a new type of structure, which has some functions including drainage, noise reduction and sliding resistance. This article describes the OGFC mix design, the key points for attention during eonstruction, and made a contrast analysis of costs between OGFC using high - viscosity modified asphah and SMA using modified asphalt, and finally concludes that OGFC surface course is lower than SMA pavement.

关 键 词：排水性沥青路面(OGFC) 配合比设计 经济分析
