| Abstract;It was intended to research into the efficient utilization of crushed expanded plastic waste, by way of lightweight geomaterials. In this study, lightweight mixed soils were made using crushed expanded plastic waste, and a series of consolidated-drained and consolidated-undrained triaxial compression tests were conducted to investigate the fundamental mechanical soil properties. As a result, it was clarified that the strength properties of the lightweight mixed soils, such as the internal friction angles, were larger than that of soil alone, considering they were under the same effective stress condition. On the other hand, the deformation properties of the mixed soils, such as the compression index and the initial rigidity, were 2.5-3 times more compressible than that of soil alone. Considering all of the test results and judging from the strength properties, it was found that the crushed expanded plastic waste was applicable enough for lightweight geomaterials. It was also found that the practical applicability should be examined from both the criteria of stress and strain, because the mixed soils might deform over the permissible limit, though the result of stability analysis in effective stress was that it was safe.
