The present research work is carried out to examine the characteristics of Black Cotton (BC) soil using the soil stabilizer namely Terrazyme. Terrazyme is non-toxic and harmless to humans, animals, marine life, and the environment. It is non-irritating, non-flammable, and non-corrosive. Terrazyme contains no combustible or corrosive materials and can be safely used near an open flame or in poorly ventilated areas. It contains neither bacteria nor known allergens. Terrazyme is an eco-friendly chemical soil stabilizer. Terrazyme soil catalyzes the reaction between the clay of the soil and the organic cat ions and accelerates the cation exchange process to decrease the adsorbed layer thickness. Stabilizer replaces adsorbed water with organic ions, thus neutralizing the negative charge on a clay particle. In the present work, black cotton soil with varying index properties has been tested for the stabilization process, and the strength of the stabilized soil was evaluated after a curing period of 7 days, 14 days, 21 days, and 28 days to find the optimum dosage of stabilizer. Different dosages, such as 200 ml/3.0 m3, 200 ml/2.5 m3, 200 ml/2.0 m3, and 200 ml/1.5 m3, were adopted. An attempt has been made to study the properties of soil modified with Terrazyme soil stabilizer to use this technology for low-volume roads. Based on laboratory results, there is observed that that there is a significant improvement in dry density and CBR values and resulting in an overall reduction in pavement thickness, increased stability of the soil, and a reduction in the cost of construction.
