Particle Size Effect of Tire Derivative on the Dynamic Properties and Liquefaction Behavior of Sand Mixed with Tire Derivatives

Disposal of scrap tires is of great concern across the globe. As scrap tires are durable in nature, their derivatives are recommended for various civil engineering applications. Filling materials in the embankments, drainage materials, etc., are few applications suggested by various recent studies. The present study investigates the effect of tire derivative particle size on the dynamic properties and liquefaction behavior of sand-tire derivative mixes. A series of strain-controlled cyclic triaxial tests were carried out considering strain amplitude, confining pressure, percentage of tire derivative and type of tire derivative as variables. A sample of 100 mm × 200 mm was considered in the study. All the samples were prepared at a density index of 60% by using dry pluviation method. The dynamic properties and liquefaction behavior, in terms of the excess pore pressure ratio, for all the mixes are detailed in the paper. A proper comparison of the behavior of different sized tire derivatives and their mixes are presented.
