Geotechnical Properties of Rubber Reinforced Cemented Clayey Soil
This paper focuses on the effect two forms of waste rubber tires of granulate (Rg) and fiber (Rf) categories on the compaction–strength–consolidation–swell–durability behavior of uncemented/cemented clayey soil. The effect of incorporation of five proportions 0%, 2.5%, 5%, 7.5% and 10% Rg/Rf (by weight of soil) and three proportions 0%, 3% and 6% cement (by weight of soil) was assessed. Reduction in maximum dry unit weight (γmax) and optimum water content (ωopt) of clayey soil and cemented clayey soil was observed with the incorporation of rubber granulates (Rg) and rubber fibers (Rf). Both unconfined compressive strength (UCS) and split tensile strength (STS) of the clayey soil were primarily controlled by the amount of cement and waste rubber tires and it was found to be decreased with the enhancement in rubber content. But addition of Rg and Rf was found to improve the ductility and strain hardening behavior of cemented clayey soil, prosperously under unconfined compression. Inclusion Rg was found to be ineffective to overshadow the brittleness of the cemented clayey soil subjected to tensile loads. The inclusion of higher rubber content had lowered the strength of cemented significantly. Decline in the California bearing ratio (CBR) value, swelling pressure (σs) and increment in the compression index (Cc) and weight loss during wet/dry cycles were observed with the incorporation of Rg and Rf in cemented clayey soil. The results of all performed tests were cross checked and compared with various Indian standards to reach at the optimum dose of Rg and Rf that can be added to cemented clayey soil for its possible applications in back filling, construction of embankment (for rural roads), sub-grade course, sub-base course and slide slope of canal. The form of waste rubber tire i.e. Rg and Rf had significant effect on the geotechnical characteristics of cemented clayey soil. Overall, Rf had outperformed the Rg, considering all evaluated geotechnical properties. Maximum dose of Rg and Rf to be added in cemented clayey soil should not be more than 5% and 7.5%, respectively.
