  • Abstract:
  • The volume of used vehicle tyres in the world is increasing every year and their disposals have therefore become a major environmental problem worldwide. Utilization of scrap tyres should minimize environmental impact and maximize conservation of natural resources. This paper presents the stabilization of expansive soil using crumb rubber powder (CRP) and cement at varying percentages (2%, 5%, 7% and 9% and 2%, 4% and 6% respectively). The soil properties, compaction, California bearing ratio (CBR) and direct shear test were used to gauge the behavior and performance of the stabilized soil. When soil blended with CRP, it was observed that maximum dry density and optimum moisture content decreases with increase in percentage of crumb rubber on soil. Blending has minimal impact on bearing capacity and shear strength. However the values remained within acceptable limits. In second case, cement added to the soil rubber mix in the percentages 2, 4 and 6% by weight of soil. In this case CBR and Direct Shear Tests were conducted. The CBR and shear strength were increased when the optimum mix (B.C soil +7% of CRP) was blended with cement.
