Mixture containing rubber particle from wasted tire and sand was prepared and a series of cyclic triaxial tests were conducted. The results show that with the increase of rubber content(wR), the failure vibration（Nf） increases at first then decreases. Also, the rubber content corresponding to the failure vibration differs from different cyclic stress ratios. When rubber content increases, the curves of the relationship between the double shear strain amplitude and the cyclic vibration ratio gradually transform from abrupt growth type to linear growth type. Meanwhile, it is found that rubber content has a significant effect on the main dynamic characteristics of mixtures. When wR=0%20%, the rubber particle sand mixture is similar to pure sand. With wR=30%50%, the dynamic characteristics of mixture gradually change from sand to rubber particles as rubber content increases. When rubber content exceeds 70%, the characteristics of the mixture are consistent with pure rubber particles. Based on the basic theory of micro soil dynamics and the characteristics of energy dissipation, the experimental phenomena and their laws are preliminarily explained.
