摘要
针对高等级水泥混凝土路面普遍存在严重水损害现象,结合国道321线试验段旧水泥混凝土路面的改造实践,对拦截雨水侵入路面、迅速排除路表水和进入路面结构的水分、增强路面结构本身的抗水性能等方面进行了防水排水设计.最后根据工程实践的成果对旧水泥混凝土路面的防水排水设计提出了建议.
According to the practice of G321 test road reconstruction, water had bad effects on the pavement because serious water-induced distress exists widely in traditional concrete pavements. It discusses the water diversion and water removal design of pavements to prevent the permeability of free water infiltrating into pavements, to remove rapidly the pavement surface water and the water infiltrating into pavements, and to strengthen the water-proof property of pavement structures. Based on the project practice, some suggestions on water diversion and water removal design of old concrete pavements are put forward.
