Application of Foam Lightweight Soil in the Reconstruction and Expansion of Existing Highways
Relying on the reconstruction and expansion project of Beijing-Shanghai Expressway from Xinyi to Jiangdu,foam lightweight soil is used in large scale to help widen the roadbed in the transition section of road and bridge and the general longitudinal section lifting section,to elaborate the performance and construction characteristics of foam lightweight soil,and to investigate the characteristics of settlement and deformation after treatment of roadbed and soft ground after the reconstruction and expansion of the expressway using foam lightweight soil by combining with the means of numerical simulation.Combined with numerical simulation,the study investigates the settlement and deformation characteristics of roadbed and soft ground treatment in the highway reconstruction and expansion project,and verifies the applicability of foam lightweight soil as filler for widening roadbed and road and bridge transition section.
