In this paper, the deformation characteristics of a mixture of tire chips and sand are discussed. First a series of drained triaxial compression tests (CD tests) on a rubber sphere specimen and the tire chips specimen was conducted to observe the deformation behavior of a rubber particle aggregate. From the movement of the rubber sphere traced on computer tomography (CT) images, the basic deformation characteristics of the rubber particle aggregate were considered. Then, a series of CD tests on the tire chips and sand mixture was conducted and the changes in the shape of each specimen before and after compression were shown by CT images. Moreover, the Particle Image Velocimetry (PIV) method was applied to CT images scanned during the test, and the deformation characteristics of the tire chips and sand mixture based on the PIV results were shown. The effect that adding tire chips had on the deformation characteristics of the mixture is described while considering the deformability of the rubber particle aggregate.
