路基路面拼接施工技术在公路改扩建工程中的应用

Application of Roadbed and Pavement Splicing Construction Technology in Highway Reconstruction and Expansion Project

以滨州至莱芜高速公路改扩建项目为例,针对施工过程中新旧路基结合处存在的差异性沉降问题,就路基路面拼接作业提出具体的施工要点及控制措施。施工实践表明:工后各项检测均满足实际要求,施工效果良好。

Taking Binzhou to Laiwu expressway reconstruction and expansion project as an example,aiming at the differential settlement problem existing in the joint of new and old subgrade in the construction process,the paper puts forward the specific construction points and control measures for the subgrade and pavement splicing operation.The construction practice shows that the inspection after construction meets the actual requirements and the construction effect is good.
