Abstract
As a basic study for the constructing a model of soils mixed with elastic particles such as rubber tips, it was intended to estimate the compressive property caused by the deformation of the elastic particles. A series of onedimensional compression tests was executed using aluminum and rubber rods, considering the effects of initial arrangement of rod-stacking. In the experiment, pictures of the states of compression were taken with digital camera. The images were analyzed by computer to calculate the volumetric change of rubber particles themselves and pore spaces, and tried to construct a quantitative model for calculating these volumetric change from properties of rubber and geometrical relation of rod-stack model's deformation. As a result, it was revealed that two compressive components concerning to the compression of rubber mixed soil could be predicted by considering the Poisson's ratio of rubber with skill.
