高速公路改扩建工程路基路面拼接技术应用

Application of Subgrade Pavement Splicing Technology in Expressway Reconstruction and Extension Project

为提升高速公路改扩建工程路基路面拼接质量,论文结合实际,以某高速改扩建项目实例为研究背景,阐述了高速公路老路面病害形成机理,在分析改扩建工程路基面拼接方式的同时,分别从老路面的地基处理、路面拼接施工准备以及基层的拼接施工技术等方面,详细地论述了路基路面拼接技术实践要点。希望分析后,可以给此类工程提供借鉴。

For improving the quality of projects of highway roadbed splicing, combined with the actual paper, with an actual highway reconstruction project as the research background, this paper expounds the formation mechanism of highway old pavement diseases, an analysis of subgrade surface reconstruction engineering joining together at the same time, respectively from the old to the foundation treatment, the splicing construction preparation and construction technology, etc., the joining together of grassroots subgrade pavement are discussed in detail stitching technology practice. Hope that the analysis can provide a reference for this kind of project.
