Black cotton soil poses problem like permeability, low bearing strength, swelling and shrinking etc. when exposed to compressive stress. There are problems involved with construction on black cotton soil, such as settlement of road, settlement of foundations etc. Terrazyme is a natural, non-toxic ,non-corrosive liquid enzyme formulation and This terrazyme made from vegetables extracts that improves the engineering qualities of soil and increase stability of soil. For studying the plastic limit of black cotton soil, it is mixed with terrazyme with different dosage i.e. 0.25 ml, 0.50 ml, 0.75ml, 1ml per 100 ml of water. These criteria are also applicable to roads and airfields having a stabilized surface layer. This Study establishes criteria for improving engineering properties of soils used for pavement base courses, sub-base courses, sub-grades by the use of additives which are mixed into the soil to effect the desired improvement.
