|
摘要
承(德)秦(皇岛)出海路祖山-马蹄岭段经过12 a的运营已经严重破损,给交通安全带来极大隐患,急需维修改造。根据路线走向、设计标准、交通量、旧路情况、改造原则,经过碎石化方案的技术方案比较,对该项目采用多锤头碎石化方案,同时提出加铺设计原则、结构组合,并给出了加铺结构厚度。
After 12 years of operations,Zushan-Matiling section of Chengde-Qinhuangdao road have been severely damaged,bring great risks to road safety,and in urgent need of repair and renovation.According to the route trend,design standard,traffic volume,old road conditions and transformation principle,through the technical scheme comparison of rubblization programs,this paper adopts multi-hammerhead rubblization scheme on the program,proposed overlay design principles,structural combination,and presents the thickness of overlay structure.
