Traditionally, cement and lime are considered as effective stabilizers to improve the geotechnical properties of expansive soils. However, from a sustainable perspective, they discouraged owing to their higher carbon footprint value. To address these negative impacts on the environment, biopolymers are proposed as stabilizers to enhance the geotechnical properties of expansive soil. The present study aims at improving the compressibility characteristics of locally sourced expansive soil using Guar Gum (GG). One-dimensional consolidation tests were performed on GG-treated soil at gum dosages at 0.5, 1.0, 1.5, 2.0 and 2.5% by dry weight of soil mass. The experimental results indicate that the compressibility index of soil with 2.5% GG increased by 1.36 times the compressibility index of untreated soil. This is attributed to the increase in repulsion between negatively charged soil particles and the hydroxyl group (OH−) of GG at a higher dosage.
