| Abstract: | According to the numerous execution of rebuilding projects for broadening and thickening old roads,like urban roads and so on.The paper puts forward some notices in the process of broadening and thickening old roads and its rebuilding.Meanwhile,it also analyzes many aspects from old roads' broadening,they mainly include foundation settlement and road base's stability,deformation-compressed of road-base soil,plasticity deformation accumulatively for road-base soil under the effect of loading,and so on.At last,it also introduces the observation test of trial roads for old roads' broadening, which will have a certain value for reference. |
