In order to investigate the fundamental properties of pure tire chips and their mixture with sand, a series of monotonic shear and cyclic triaxial tests was performed. From the results of the monotonic drained shear tests on pure tire chips, linear development of axial and volumetric strains were observed during loading up to 20% axial strain in both types of tire chips. It was further observed that the volumetric strain induced by shear loading recovered to zero during unloading. It is considered that the volumetric strain induced by shear was not dilatancy by rearrangement of particles but due to the stretching of tire chips. In the monotonic undrained shear tests using the mixed sand and tire chips, the mixtures show completely different behavior to pure sand, this due to the particles of the tire chips being smaller than that of the sand. The matrix of the material was governed by tire chips when the tire chip fraction was greater than 0.3. From the results of the undrained cyclic triaxial tests of pure tire chips, there was hardly any development of pore water pressure, resulting in non-liquefaction.
