Abstract
Road development projects are major part of a country’s economic growth. It costs about 50% of a country’s total cost of infrastructure. The overall performance of pavement is dependent on the subgrade soil type and its properties. Various stabilization techniques are utilized to annihilate the inadequate properties of sub-grade soils. Principally, traditional soil stabilizers like lime, cement, bitumen, etc. and combinations of these have been utilized widely to enhance the properties of poor soil. These traditional soil stabilizers are uneconomical and hence cost efficient and eco-friendly materials are suggested. From recent studies it’s been found that the use of bio-enzymes and various fibers on soil shows tremendous improvement in strength properties of soil. The present study is focused on improving the geotechnical properties of cohesive soil using terrazyme ,a natural non-toxic, liquid enzyme and kenaf fiber, a plant based fiber to use it as a sub grade material. Standard proctor, Unconfined compressive strength tests and California bearing ratio tests, SEM analysis were conducted on untreated soil and soil mixed with terrazyme and its combinations with kenaf fiber. This paper is a comparative study of bio-enzyme (terrazyme) and kenaf fiber in cohesive soil subgrades.
