Abstract: Traditional stabilizers like lime, cement, fly ash, rice husk ash, and combinations of these have been widely used to improve the properties of problematic soil. Considering the environmental impacts of these stabilizers, researchers come up with an ecofriendly method called enzymatic stabilization. Recently combination of enzyme and lime known as enzymatic lime found to be effective in improvement of strength of soft soils. In the present work, the effect of enzymatic lime on engineering behaviour of clay is analysed. The purpose of this research is to verify the efficacy of enzymatic lime in soft clays. An extensive study was carried out on a soil sample using different dosages lime, enzyme and combination of lime and enzyme. The variation in liquid limit, plastic limit, plasticity index and unconfined compressive strength were investigated after 3,7,14 and 28 days of curing. The optimum dosage of the stabilizers was inferred from obtained results. Addition of 120 ml/m3 of enzyme and 2 % lime by weight of soil will impart significant improvement of properties. Sufficient improvement of strength obtained after 14 days of curing indicates accelerated strength improvement by enzymatic lime. Utilization of enzyme and lime in combination can reduce the percentage of lime for soil treatment making the proposed method environmental-friendly.
