Abstract
In this study, it was intended to clarify the compressive properties of soils mixed with deformable particles such as waste tire chips. Generally, in the case of soil mixed with deformable particles such as rubber, it is thought that two more compression components; the compression of the deformable particle themselves and the following reduction of pore space, add to the ordinary volumetric compression. Therefore, a series of one-dimensional compression tests were executed using rubber and aluminum chips to estimate these additional compression components. In the experiment, the specimen pore space was saturated with water, and the drainage was measured to estimate the pore space volume change. As a result, it was found that the pore space reduction caused by the deformation of rubber chips was far larger than the compression of the rubber chips themselves. It was also confirmed that the compression of rubber arises most extremely in the early stages, and that the rubber is hardly compressed any more even if the compressive stress increases subsequently.
