The effect of crumb rubber on ductility of Soil-Rubber mixture

Addition of waste crumb rubber for reinforcing the soils is an appropriate method for improving the strength and bearing capacity of the soils. In addition to the improvement of soil engineering properties, the addition of waste crumb rubber is a measure for the protection of environment. In this study, the shear strength parameters of the Kaolinite clay, as the control material, and the Kaolinite clay reinforced by different percentages of different types of crumb rubber content have been evaluated. The triaxial tests have been conducted on the control and crumb rubber reinforced soils. Results show that the addition of crumb rubber to the soil results in the improvement of shear strength parameters and the ductility of the soil.
