基于高速公路改扩建工程路基路面拼宽技术分析

Analysis of widening technology of roadbed and pavement based on expressway reconstruction and expansion project

为提高高速公路的通行能力,需要通过选用不同的方式对路基、路面进行加宽。提出了避免拼宽过程中由于新旧路基连接土质松软造成不均匀沉降和路面产生裂缝的方法,通过改扩建施工,实现了交通运输的可持续发展。

In order to improve the traffic capacity of expressways, it is necessary to widen the roadbed and road surface by using unreasonable methods. This paper proposes a method to avoid uneven settlement and cracks on the pavement due to the softness of the old and new roadbeds during the process of widening. Through the reconstruction and expansion, the sustainable development of transportation is realized.
