Abstract
The method by which geotechnical properties of a soil is improved using enzymes is termed as bio-stabilization. This technique is found to have a low environmental impact as well as it is biodegradable. The present work involves the evaluation of the performance of bio-stabilized lateritic and black cotton soils in pavements. The experimental studies are conducted on three-volume proportions of the enzyme, namely 100, 150, and 200 ml/m3. It was observed that the strength parameters exhibited high improvements in case of both the soils. The role of varying dosages and curing periods were also observed to be significant in achieving desirable properties. Further, an attempt is also made to study the feasibility of bio-stabilization in deciding the pavement thickness.
