摘要
透水沥青(OGFC)路面可以减小降雨时的路表径流量和降低道路两侧噪声,具有快速排除路面积水、路面抗滑性能好和行车安全性能好等优点,在海绵城市建设中得到了广泛的应用。从OGFC路面施工技术的特点出发,依托秀山县海绵城市建设项目的实施案例,分析OGFC路面在旧混凝土路面上铺筑的施工技术。提出在后期要注意养护问题,以减小对路面使用效果和耐久性的影响。
The permeable asphalt(open graded friction course-OGFC) pavement can decrease the road surface runoff during rainfall and decrease the noise at both sides of road, has the advantages of rapidly discharging the pavement waterlogging, the good anti-slide performance of pavement and the good driving safety, and is widely used in the construction of sponge city. Starting from the characteristics of OGFC pavement construction technology and relying on the implementation case of Xiushan County Sponge City Construction Project, the article analyzes the construction technology of OGFC pavement to be paved on the old concrete pavement, and puts forward the maintenance issue for attention in the late in order to reduce the influence on the service effect and durability of pavement.
