Abstract
Lithomargic soil is locally known as Shedi soil, which is found in shallow depth usually under the lateritic soil. These soils tend to destabilize the pavements that are constructed on the embankment or the subgrade made up of lithomargic soil, as they do not have the required shear strength. Thus it is required to improve the engineering properties of this soil before it can be used as a highway material. This soil can be stabilized by various chemical and mechanical means. This paper focuses on the stabilization of the soil using normal 53 grade cement and randomly distributed shredded tyre chips obtained from waste rubber tyres. The rubber when introduced into the lithomargic soil acts as a reinforcing agent and the cement provides the binding aid which fortifies the soil and improves the shear strength by improving the friction component of the latter soil. The modified proctor results have shown the highest value of maximum dry density (MDD) and lowest optimum moisture content (OMC) for the trial mixes, when compacted with 4% shredded rubber pieces and 2% cement, which can be taken as the optimum dosage. The strength is evaluated based on unconfined shear strength and the penetration resistance in terms of California Bearing Ratio (CBR) test for the samples compacted at maximum proctor density for optimum dosage of cement and shredded rubber pieces in the lithomargic soil. The results showed that the lithomargic soil can be effectively stabilized to be used as a highway material to a great extent by making use of waste shredded rubber pieces that would otherwise degrade the environment. This ground modification method is an eco-friendly and cheaper method when compared to other stabilization techniques, using which sustainability with economy can be achieved.
