Abstract: The Black Cotton (BC) soil is abundantly available in North Karnataka (India).To improve its properties the soil has to be stabilized either mechanically or chemically to improve the geotechnical properties of such type of soils. Enzyme soil stabilization is one of the methods of soil stabilization. Various experimental investigations have shown that there is much improvement in Atterberg limits, CBR and UCS strength when stabilized with Enzyme .In recent past many Enzymes have come to the market which can be used as Stabilizing agent. One such stabilizing agent (Product "A")is used in the present investigation to improve the soil properties for using it as sub base material in the pavement. The effect of enzyme on black cotton soil in terms of Unconfined Compressive Strength (UCS), California Bearing Ratio (CBR), Compaction and permeability have been studied. It has been observed that the enzyme treated soil showed significant improvement in terms of UCS, CBR with longer curing period. Since the CBR test results show that the increase in CBR value is more than 100%, fatigue behavior of enzyme stabilized soil also has been studied to find stress variation for repeated load condition. The experimental investigation shows much improvement in its fatigue behavior for BC soil .Suitability of this stabilized soil as sub base material for the flexible pavement design has been investigated. � Advanced Engineering Solutions (AES.COM) Ottawa, Canada.
