Road widening treatment method
The invention provides a road widening treatment method which comprises the following steps: step 1, arranging a vertical drainage system along the joint of a new roadbed and an old roadbed; step 2, selecting a filler consistent with the old roadbed filler as a new roadbed filler, filling and compacting, and firstly filling sand gravel or gravelly soil at the bottom to serve as a substrate layer;step 3, paving and roughly flattening the roadbed filling material. step 4, paving and finely leveling the roadbed filling material. and step 5, rolling the filling material. The method solves the problems of longitudinal and transverse cracks and other diseases of the pavement after the road widening and reconstruction engineering is completed, can improve the bearing capacity of the foundation,controls the settlement deformation of the newly-filled roadbed, and enhances the anti-benching capacity of the junction of the newly-filled roadbed and the old roadbed and the stability of the widened roadbed.
一种道路拓宽处理方法，包括如下步骤，步骤一：沿新路基和老路基连接处设置竖向排水系统。步骤二：选择与老路基填料一致填料作为新路基填料，进行填充压实，首先在底部填充砂砾石或碎石土作为基底层。步骤三，路基填筑材料铺筑粗平。步骤四：路基填筑材料铺筑精平。步骤五：对填筑材料进行碾压。本发明解决了出现在道路拓宽改造工程完成后路面纵、横向裂缝等病害的问题，能够提高地基承载力，控制新填筑路基沉降变形，增强新老路基结合部抗翦能力和加宽路基的稳定性。
