改扩建公路路基路面设计内容及对策分析
摘要
Compared with the new highway, the reconstruction and expansion of highway engineering is more complex, especially for the content of subgrade and pavement, it needs to combine the characteristics of the original highway and the surrounding natural environment to consider in many aspects, and through optimizing the design of subgrade and pavement, it can effectively solve many problems in the reconstruction and expansion of highway construction, and lay a good foundation for the smooth, efficient and high-quality completion of the later construction. In connection with the actual engineering cases, this paper analyzes the design difficulties of the roadbed and pavement of the highway reconstruction and expansion in detail, and from the pavement structure, drainage function, special foundation treatment and other aspects, puts forward several design optimization measures for reference.
