Shear Strength Characteristics and Energy Absorption Capacity of Soil-Tire Crumb Mixtures

Naresh Dixit P S, Mohammed Zubair

Abstract


Discarding and recycling of tire waste is a major environmental issue in the present. Earthquake hazards are becoming a major concern for all the countries and its mitigation measures have taken the center stage of research in the field. In this regard, tire crumbs being a waste material were mixed with soil samples at different proportions to determine its effect on shear strength characteristics and energy absorption capacity. The primary objective of this study involves determining the shear strength characteristics, energy absorption capacity and brittleness index of Soil-Tire Crumb Mixture (STCM) by performing Direct Shear and Unconsolidated Undrained (UU) Triaxial test on disturbed soil samples. Soil samples were collected from various site locations of East Bengaluru based on borehole data. Tire crumbs were mixed with the soil in varying percentages from 0-10% by mass of soil at an increment of 2.5%. Stress-strain curves for direct shear and UU Triaxial shear test for different confining pressures were plotted. Experimental results showed that the direct shear strength and UU Triaxial strength of STCM increased up to 54.14kPa and 226.26kPa respectively. This increase was observed only in the soils which contained coarse-grained particles in excess of 50%.  Further, energy absorption capacity and brittleness index were calculated from the stress-strain curve. Its application to earthquake resistant design must be studied in detail in terms of site response.
