既有道路功能提升技术研究

Research on upgrading technology of existing road engineering

以京台高速济南至泰安段改扩建项目为工程背景,在对现有道路问题进行全面调查的基础上,进行既有道路功能提升技术研究,总结出我国公路常见的功能缺失问题。项目建设过程采用了业内先进的设计理念,最大限度提升道路功能的同时节约工程材料,对此进行了理论分析与总结,对国内类似公路改扩建工程具有借鉴意义。

Combined with the reconstruction and expansion project of Beijing-Taipei expressway from Jinan to Tai'an section as the engineering background,based on a comprehensive investigation of the existing road problems,the paper studies the existing road function improvement technology,and summarizes the common problems of functional deficiency of China's highways.The construction process of the project adopts the advanced design concept in the industry,which maximizes the road function and saves engineering materials.This paper carries on the theoretical analysis and summary,which can be used for reference for similar highway reconstruction and expansion projects in China.
