With increasing vehicular traffic on the roads, the production of rubber is steeply increased over the years. Consequently, more and more scrapped rubber tires are discarded every year, and most of them are ended up in municipal landfills. As a remedy to this, researchers are trying to use these wastes in better ways, such as filling material in earthen embankments, rather than letting them get dumped in landfills. This study aims to investigate the effect of dynamic loads on the performance of rubber tire chips, a scrap tire derivative, in its saturated state. For the study, a series of strain-controlled cyclic triaxial tests were performed. The parameters like cyclic strain amplitude (0.075, 0.1125, 0.15, 0.1875, 0.225, 0.2625, and 0.3%) and confining pressure (50, 75, and 100 kPa) were selected as variables. The rubber tire chips with average dimension of 12 mm x 20 mm were considered for the study. The dynamic properties obtained are compared with that of the Indian standard sand. The number of loading cycles for initiation of liquefaction is used to compare the liquefaction potential of the rubber tire chips with that of the standard sand. The cyclic tests showed that the tire chips do not liquefy for large number of loading cycles. The tire chips showed very high damping ratios in comparison with sand but are considerably low in their shear modulus.
