• Effect of Bio-Enzyme use on soil stabilization was conducted at Soil Mechanics
• Bio-Enzymatic soil stabilization in Road Construction (Everyman’ Science VOL XLI No.6 March 06 Page No.60-69- Dr. C.Venkatasubramnyam School of Civil Engineering SASTRA Tanjavur.) • In this study 5 types of soil (From low to high clay content) are considered. • Based on strength variation study has been done on cost saving by the use of enzyme stabilized sub base. • The overall saving in the total cost of construction is 30- 40%
