高速公路路面状况评价及扩建方案分析

Expressway Pavement Condition Evaluation and Expansion Scheme Analysis

文章从路面表观性能、路面结构性能和路面材料性能的角度出发,对老路路面的技术状况进行综合评价,确定路面利用的可行性,并结合高速公路改扩建工程具体情况,提出老路扩建的具体方案,全线采用硬路肩整体挖除方案,在原路面基础上进行整体加铺,拼宽路面采用与原道路相同的路面结构,旨在为道路改扩建工程提供参考和借鉴。

This paper makes a comprehensive evaluation of the technical condition of the old road pavement from the perspectives of pavement appearance performance,pavement structure performance,and pavement material performance,determines the feasibility of pavement utilization,and puts forward a specific scheme for the old road expansion according to the specific situation of the expressway reconstruction and expansion engineering.The whole line adopts the overall excavation scheme of the hard road shoulder,and overall paving is carried out on the basis of the original pavement.The widened pavement adopts the same pavement structure as the original road,which aims to provide reference for the road reconstruction and expansion engineering.
