Using Granular Waste Tire as a Factor to Increase Shear Strength of Cohesionless Soils

Soils are called problematic soils when they do not have sufficient bearing strength to provide a founda-tion for the structures be built on them and these types of need improved with appropriate methods depending their properties. Improvement applied strengthen often cause financial burden. Recently, there studies about use waste rubber tires, which pose an environ-mental risk during storage, as reinforcement material soils. The main purpose this study is examine effect poorly graded sand (SP) mixed granular tires in different proportions (10%, 20%, 30%, 40% 50%) shear sand. For purpose, physical (water content, specific weight, unit weight) mechanical (shear strength) parameters mixtures were determined. According results research, 100% content contributes by certain proportion compared materials containing granular-sized rubber. highest slip resistance value was observed 20% tire mixtures, while higher rates addition provided lower than material. In addition, considering issue terms environmental im-pact, column test carried out mixture rubber-80% no adverse ef-fects pollutants observed.
