During construction, Engineers often face difficulty related to the stability of soil with or on which the structure is being constructed as the unstable soil cannot not withstand the loads imposed over it. Since the layers of pavements distributes the load evenly over the subgrade, the design of pavement layer is very much dependent on the strength of the subgrade soil over which they are to be laid. So, there is an urgent need to improve the properties of subgrade. An effort to treat the earth with an enzyme that proves very much advantageous for engineering purposes. It is a natural solution which is generated by the enzymatic action on fruits, edibles, saccharine and water by means of fermentation. In this research, a bio-enzyme labelled as Terrazyme is being utilized that significantly improves the properties of soil. Terrazyme being cost effective, efficient, non-toxic, non-inflammable increases the stability by accelerating the enzymatic reactions between the argil and cations(organic) and accelerates the cationic interchange operation to lower down the diffused double layer thickness. The paper deals with all the information about terrazyme including its working mechanism and different properties of soil. It has been investigated that on incrementing the dosage of terrazyme in test sample, notable improvement in the value of UCS and CBR value of soil is observed.
