Study on Effect of Crumb Rubber on Behavior of Soil

A major problem associated with socio-economic development of a country is waste disposal. Safer disposal of rubber tyre waste has become a challenging job. This paper presents the stabilization of soils using crumb rubber at varying percentages (5%, 10%, 15% and 20%). The soil properties, compaction and unconfined compression strength were used to gauge the behavior and performance of the stabilized soils. From the tests conducted on the two soils, it was observed that maximum dry density and optimum moisture content decreases with increase in percentage of crumb rubber on soils. The UCS value increased with increase in percentage of crumb rubber and the maximum values were observed at 10% and 15% for the soil sample S1 and soil sample S2 respectively.
