The effect of crumb rubber on the shear strength parameters

Today, several methods are available for improving the physical and mechanical behaviour of the soils unsuitable for construction projects. These methods include compaction, consolidation, preloading, grouting, and stabilization by adding chemical materials etc. 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 two different types of crumb rubber content have been evaluated. The consolidated drained (CD) and unconsolidated undrained (UU) triaxial have been conducted on specimens and results showed that shear strength improved with crumb rubber.
