The accumulation of the discarded tires in large volume increases loads on the landfills and hence raising a concern to find an alternative beneficial use of these used tires. This study investigates the effect of dynamic loads on a mixture of rubber tire chips, a scrap tire derivative and sand in its dry state, for the possible use of tire chips in various geotechnical applications. The investigation included a series of strain-controlled cyclic triaxial tests. The parameters like loading frequency, cyclic strain amplitude and confining pressures were kept as variables. A sample of 100 mm diameter and 200 mm height was considered in the study. The tire chips with 12 mm × 20 mm as average dimension and having a specific gravity of 1.14 were used. Indian standard sand (Grade II) was considered for the study. The samples were prepared by dry pluviation method at 90% relative density. The tests showed that with an increase in confining pressure, the shear modulus increases, and the damping ratio decreases. An increase in strain amplitude decreases the shear modulus but increases the damping ratio. The detailed variation of the shear modulus and damping ratio of the mixture with varying frequency and number of loading cycles are also presented in the paper.
