摘　　要：路肩拦水带以预制安装的水泥混凝土拦水带为主要形式,沥青砂拦水带使用较少,其在我国各地区应用经验不多。介绍了小大(小沙河至大通)一级公路克图至大通段路肩沥青砂拦水带滑模施工工艺,对沥青砂拦水带施工质量控制的经验进行总结,认为:沥青砂拦水带滑模施工工艺简单、施工速度快,沥青砂拦水带线形圆滑美观、拦水效果较好。The main form of the shoulder water block is the prefabricated cement concrete curb with less use of impound strap construction by asphalt concrete,so there are few relevant application experience in various regions of China.In this paper,a complete set of slip form construction technology for asphalt sand water blocking belt on the shoulder of Ketuto Datong Section of Xiao-Da(Xiaoshahe-Datong)First-class Highway has been introduced with key experience points of construction quality control being summed up,it has been concluded that:The slip form construction technology of water blocking belt constructed by asphalt sand is simple and has fast construction speed with smooth and beautiful alignment shape and good water blocking effect,which could be widely used in other highways.

关 键 词：路肩 沥青砂 拦水带 滑模施工 质量控制
