上海地区道路大中修的几点设计经验总结

Summarization of Several Design Experience in Road Overhaul of Shanghai

结合实际项目经验,总结出上海地区道路大中修工程的几个设计要点:首先分析目前既有路基状况调查中存在的问题和后果,提出要重视既有路基状况调查;其次结合工程案例提出在路基路面补强方案总体可行的情况下,优先选择补强方案,充分利用既有路基;结合上海气候、路基材料,如要翻建路面同时利用既有路基,施工中须把握翻挖路面的时机尽早铺筑新路面结构;注重基层就地冷再生利用。

According to the practical engineering experience,the article summarizes several design gist of the road overhaul in the areas of Shanghai.The article firstly analyzes the existing problems and consequences in the survey of the present roadbed status,puts forward the attention to the survey of the existing roadbed status,and then puts forward the priority selection of reinforcement scheme and the full utilization of the existing roadbed under the overall feasibility of roadbed pavement reinforcement scheme by the engineering cases.Combined with the climate of Shanghai and the roadbed material,it must be to master the opportunity of pavement excavation in the construction if the pavement is required to excavate and also the existing roadbed is utilized.It is to pay attention to the local cold recycle of base course.
