Advancing the Strength of Expansive Soil using BioEnzyme and Pond-Ash

Abstract

Expansive soils are problematic and prone to ground movements, which can seriously harm underlying structures and reduce their carrying ability. The expansive nature of soils is activated by moisture fluctuations, causing it to expand and contract. There are many stabilizing chemicals that have been used to treat Black Cotton soil, including lime, cement, and fly ash. Recently, it has become clear that using bio-enzymes to stabilize soil has a lot of potential. The effectiveness of enzymatic stabilization of expanding soils in road pavements is examined in this paper. To establish the permanency of stabilized soil, many experiments were performed. The application of an enzyme-based stabilizer showed its ability to maintain material stiffness despite changes in moisture, considerably increasing the strength of soils. In this study, the effects of combining Black Cotton soil that has been stabilized with Roadzyme and Pond Ash are examined throughout a range of curing times. The soil's Unconfined Compressive Strength (UCC) and California Bearing Ratio (CBR) readings were shown to be significantly improved over time using Roadzyme.
