Expanded polystyrene(EPS) is an excellent light filled material. EPS has a lot of good properties, such as light mass, high strength, good chemical stability, nice watery stability, wonderful mechanical properties and convenience in construction, which is widely used in road engineering in foreign countries. Utilizing EPS can decrease excessive subsidence and discrepant subsidence of soft subgrade, reduce lateral pressure and displacement of bridge pier, and so on. Less researches and applications of EPS have been carried out in China. Physical and chemical characteristics, mechanical properties, design method as a light filled material in subgrade and applications in road engineering of EPS are introduced and analyzed in the paper,which has consultative function of utilizing EPS in China.
