改扩建道路新旧路基路面结合处施工技术研究

Research on Construction Technology for the Joint of New and Old Roadbeds and Pavements in the Reconstruction and Expansion of Roads

如果改造和扩建的路基拼接效果不佳,将会导致沉降差异,甚至出现路面开裂现象,增加了行车的安全风险。文章以某道路改扩建项目为实例,提出了新旧路基拼接方案,并就新老路基增压补强处理措施展开了研究。通过新旧路基沉降实时监测数据反映,新旧路基拼接施工性能表现优异,衔接效果理想。

If the reconstruction and expansion of the roadbed splicing effect is not good,it will lead to settlement differences,and even pavement cracking,which will increase the safety risk of driving.Taking a road reconstruction and expansion project as an example,this paper puts forward the splicing scheme of new and old subgrade,and studies the pressurization and reinforcement treatment measures of new and old subgrade.According to the real-time monitoring data of new and old subgrade settlement,the splicing construction performance of new and old subgrade is excellent,and the connection effect is ideal.
