This study looked at how adding tire powder affected saturated sandy soil's ability to liquefy. To investigate the dynamic characteristics of the sand-ground rubber mixture, such as the damping ratio and equivalent shear modulus, a number of stress-controlled undrained cyclic triaxial experiments were conducted. Five percentages of ground tire rubber (10, 20, 30, 35, and 40% by weight) were chosen for the study based on the mixture in which compressibility may be tolerated for geotechnical design (sand-like behavior). The mixes were created at two different relative densities, 35 and 50 percent, and the tests were conducted under a constant confining pressure. Investigations were conducted into the effects of many parameters, including relative density, rubber percent, and rubber-sand particle ratio. Comparing the sand-tyre mixture to shredded tyre and sand mixtures, test results show that the shear stiffness of the former reduces significantly, even at modest percentages of ground rubber. The maximum shear modulus of the reinforced soil rose as the mixture’s tire powder content increased. However, the maximum shear modulus was unaffected noticeably by an increase in the percentage of tire shreds. Additionally, after adding up to 20% of rubber, the mean damping ratio rises as tire powder does. Furthermore, it was noted that specimens with larger relative densities exhibited dynamic characteristics with a steadily increasing damping ratio trend. The liquefaction resistance of mixtures with a 35% relative density and 30% rubber content, and mixtures with a 50% relative density and 10% ground rubber content, is nearly equal, despite the significant variations in the specimen’s ground rubber percentage. Tire rubber powder applied for soil reinforcement often lessens liquefaction-induced soil deformations.
