Waste disposal has become a serious problem because of lack of land-fill and it should be solved urgently. It is therefore desirable to develop an effective method of geotechnical treatment to use the waste materials. The waste expanded polystyrene (EPS), which is widely obtained in Japan, may be utilized as a material for lightening by mixing with soil. The aim of this study is to investigate the compression and direct shear properties of a mixture of sand and heat compressed and crushed EPS (HCCE) for possible use as a light weight fill material. The test results showed that the HCCE material was effective to lighten the self-weight of soil and also to increase the shear strength of geomaterial. In addition, the sand mixed with the HCCE material was found to be a useful fill material on soft ground based on the results of the slope stability analysis.
