Research on soil stabilization by enzymes though started more than two decades ago, very little research has been done on simulating field conditions for the laboratory studies on behaviour of enzyme treated soils. Road construction on soils with poor engineering properties necessitates adoption of Stabilization techniques. Bio-enzymes are found to improve the soil properties and thus performance of roads. Effect of bio-enzymes on soils depends on type, dosage of bio-enzyme, its curing period and amount of fines. To evaluate the effect of bio-enzyme, the soil was treated with varying dosages of Bio-enzyme, a commercial Bio-enzyme and the effect of Bio-Enzyme dosage on plasticity characteristics and unconfined compressive strength of soils were evaluated. It was found that with increase in Bio-enzyme dosage, the plasticity index of the soils decreases up to certain limit and then the reduction was not substantial. Studies further revealed that the increase in Unconfined Compressive strength is dependent on fines content.
