STUDY ON IMPACT OF TERRAZYME STABILISED SOIL ON CALIFORNIA BEARING RATIO

Abstract

The economic status of a country is better evaluated by the prevailing road connectivity and also by steps
taken to improve it, thus generating sources of income and employment. With the continuous growth in road users,
high quality materials are required to withstand the load on pavements. The non-uniform distribution of soil in
subgrade of pavement makes it weaker and needs to be stabilized in order to attain the strength. The current study
made use of natural enzymes to stabilize the soil, as it is cost effective and eco-friendly. An unconventional bioenzyme calledterrazyme which is a product of degradation of natural waste is used as a soil stabilizer. Index
properties of soil were evaluated to classify the soil and California Bearing Ratio was evaluated for samples with and
without terrazyme. The thickness parameter ws analyzed using CBR and it was found that the load bearing capacity
of soil has improved by 141% at highest dosage of terrazyme.
