浅析高速公路改扩建项目路线及路基路面设计重点

Brief Analysis on Freeway Reconstruction and Expansion Project Route and Subgrade Pavement Design Points

我国的现代化建设在不断发展,人们对出行的便利性有了更高的要求,对我国高速公路的道路使用面积的关注程度越来越高。现如今,我国高速公路已经满足不了人们的日常出行需求,所以,高速公路路网进行不断的提升以及高速公路的扩建就显得尤为重要。但由于以往经济与技术的原因,原有高速公路的路面在设计上存在一些有待解决的问题,想要解决这样的问题,可以利用改建和扩建高速公路的方式。本文从高速公路的设计要求及要点、路基路面设计优化的意义、高速公路改扩建路线、路基路面设计案例分析方面进行分析和研究。

The modernization construction in China is constantly developing,people have higher requirements for the convenience of travel,and pay more attention to the road occupying area of freeway in China.Nowadays,China’s freeways can no longer meet people’s daily travel needs.Therefore,the continuous improvement of the freeway network and the expansion of freeways are particularly important.However,due to past economic and technical reasons,there are some problems to be solved in the design of the original freeway pavement.To solve such problems,it is necessary to reconstruct and expand the freeway.This article analyzes and studies the design requirements and main points of freeway,the significance of subgrade pavement design optimization,the freeway reconstruction and expansion routes,and the subgrade pavement design case analysis.
