摘　　要：以吉布提既有N1公路改扩建项目为研究案例,从路基施工工艺出发,对路基工程土石方开挖施工、填筑施工流程、技术要点进行深入剖析,在施工过程中对路基改扩建施工质量进行把控,包括石方开挖时排水设置、压实度的试验、级配碎石等应符合设计要求,形成了一套路基改扩建快速安全的施工技术方案。This paper takes the existing N1 Highway Reconstruction and Expansion Project in Djibouti as a case study.Starting from the roadbed construction technology,this paper makes an in-depth analysis of the construction process and technical points of the roadbed excavation and filling,and controls the construction quality of the roadbed reconstruction and expansion during the construction process,including the drainage setting during stone excavation,the test of compaction degree,and the grading of gravel should meet the design requirements.Formed a set of roadbed reconstruction and expansion rapid and safe construction technology scheme.
