In order to investigate the improvement methods and dynamic characteristics of waste tire granular materials under the freeze-thaw cycle condition. The experiment was carried out to improve the ratio of waste tire granular materials. The samples of improved waste tire mixed materials were prepared. The dynamic triaxial test was then performed to analyze the dynamic stress-dynamic strain characteristics influenced by temperature, freeze-thaw cycle and cycle loading. The results show that, within 5% of the dynamic strain, the dynamic stress-dynamic strain relationship curve of the mixed material sample is charactered by strain hardening without obvious peak point. In the range of ?15～ 20 ℃, the strength of sample increases with the decrease of temperature, and decreases with the increase of freeze-thaw cycles and cycle loading times. The freeze-thaw cycles and cycle loading times have little influence on the strength of normal temperature samples, but have significant influence on frozen samples.
