摘要
为提高改扩建道路设计水平,文章总结了改扩建道路的路线线形拟合方法,从开挖台阶、铺土工材料、地基处理、压实质量控制等方面探讨了拼宽路基设计要点。同时,探讨了路面拼接方法及新旧路面拼接处排水系统布置方法,研究成果可为改扩建道路提供理论指导。
In order to improve design level of the reconstruction and expansion road,this paper summarizes its route linear fitting methods and discusses the design points of subgrade widening from aspects of step excavation,geotechnical material laying,foundation treatment and compaction quality control.At the same time,the pavement splicing methods and the drainage system layout methods at the junction of new and old pavements are discussed.The research results can provide theoretical guidance for the reconstruction and expansion of roads.
