Application of Bubble Mixed Light Soil in Road Subgrade Load Reduction
In the new road project,to reduce the impact on the existing buildings and structures,light materials are usually used in the subgrade filling.The commonly used light materials are lime-ash soil,bubble mixed light soil and polystyrene foam (EPS).Combining with engineering examples and through scheme comparison,this paper introduces the characteristics of light bulk weight and self-stability of bubble mixed light soil material in the design of urban road construction on the top of the existing river embankment,and solves the requirements of road subgrade load reduction and the stress and deformation of the existing river embankment retaining structure,so as to achieve the purposes of engineering safety,reliability,technical feasibility and cost saving.
