摘要
为提高城市道路改建中新老路面路基的拼接质量,结合工程案例对新老路基路面拼接技术进行研究与分析,从原有路面开挖和旧边沟、排水渠、路基边坡的处理、新旧路基结合部位处理、新旧面层拼接施工几方面总结了拼接施工的技术要点,并提出一般路基填筑、路堤拼接施工的沉降控制的控制要点以及质量控制对策。
In order to improve the quality of the splicing of new and old road surfaces and subgrades in urban road reconstruction,combined with engineering cases,research and analysis were conducted on the splicing technology of new and old road surfaces and subgrades.The technical points of splicing construction were summarized from several aspects such as excavation of the original road surface,treatment ofold side ditches,drainage channels,and roadbed slopes,treatment of the joint parts of new and old roadbeds,and splicing construction of new and old surface layers.The control points and quality control countermeasures of settlement control in general subgrade filling and embankment splicingconstruction areputforward.
