A review on use of Terrazyme as bio-enzyme for the stabilization of soil sub-grade of pavement

Civil Engineering

The major problem for civil engineers to build any highway is general soil with weak engineering properties. The maximum load of traffic is transferred to soil sub grade therefore soil stability and durability becomes necessary. So, soil stabilization is required before use. There are several methods of soil stabilization out of which terrazyme provides more stability and durability to the sub grade of the soil.When thesoil needs a broad treatment scalethen products like lime, asphalt, fly ash etc. prove to be verycostly and are unsuccessful to any point. A very powerful soil stabilizer is the bio enzyme using it as a soil stabilizer. As the study shows, Terrazyme, a bio-enzyme emerges as a veryeffective soilstabilizing agent. Terrazyme is used as a soil stabilizing agent in the present study. Terrazyme brings with it other significant advantages throughout its treatment application to the soil. The biggest downside it brings with it is that expensive but, as a small dose of Terrazyme, this issue can be counteracted to a large degree by enhancing the engineering properties of the soils. This review highlights effects of terrazyme, advantages, limitations and its applications in soil sub grade in a sustainable way
