摘　　要：以某公路工程改扩建为例,深入分析新旧路面拼接施工中原地基及排水沟处理、新建路基施工、新旧路基结合处的压实度控制及新旧面层拼接施工中的技术要点,提出了路基拼接施工质量控制措施,为提高新旧路面拼接质量提供理论支撑和实践指导,有助于保障公路改扩建工程的顺利进行。Taking the reconstruction and expansion of a highway project as an example,this paper deeply analyzes the technical key points in the construction of old and new pavement splicing construction,the treatment of central soil foundation and drainage ditch,the construction of new roadbed,the compaction degree control of the junction of new and old roadbed and the construction of new and old surface layer splicing construction,and puts forward the quality control measures of roadbed splicing construction.It provides theoretical support and practical guidance for improving the quality of new and old pavement splicing,and helps to ensure the smooth progress of highway reconstruction and expansion projects.
