Today engineers are responsible for specifying or selecting the correct technique, quantity of material required and stabilizing method. Throughout the world the soil vary from place to place and the engineering properties of soil are also equally variable. The success of soil stabilization is determined by soil testing. The soil stabilization method should be verified in laboratory before it is used for construction and preferably before ordering or specifying the materials. Various techniques are used to stabilize the soil. Stabilization of soil with Bio enzymes and waste materials is a newly method to improve the geotechnical properties of the soil. In this present study, the effectiveness of Bio enzymes and waste materials like in stabilizing the soil of South Canara districts are investigated through laboratory experiments. The Lithomargic soil (Shedi soil) is procured from the field is used for the investigation. Bio enzyme (Alkazyme) are used as a soil stabilizer. The pavements of Udupi and Dakshina Kannada districts are found to be damaged due to improper drainage system and heavy rainfall added problems and another major failure of sub base due to improper material usage. The soils available in this region are Lateritic soil and Lithomargic soil. The plasticity index ofthe soil is found to be more due to high presence of silt and clay content in this type of soil. In this study, the Lithomargic soil sample are collected to investigate the geo technical properties and treated with variable dosage of Bio enzyme. The strength parameters of the stabilized soil have been evaluated for a curing period of 0, 7, 14, 21 and 28 days. The tests were carried out to determine optimum moisture content and maximum dry density, unconfined compressive strength and California bearing ratio.
