Consideration of the compression property of soil mixed with deformable particles – One-dimensional compression behavior of rubber and aluminum chip mixtures

In order to examine the modeling of compression behavior of soils mixed with deformable particles, one-dimensional compression tests of rubber and aluminum chips mixture packed into a cylin-der were executed. Then, the compression behavior of the soil mixed with deformable particles such as rubber chips was observed quantitatively, and consider the effect of deformable particles on the compres-sion property of the entire mixture. As a result, it was shown to be important to clarify the compression mechanism of the mixture including deformable particle. Further, it was found that the compression of the mixture were greatly affected by the nature of dominant skeleton constituted by the particles, and the vol-ume change caused by the movement of constituent particles were developed rapidly when the skeleton of the mixture was loosened even a little.
