Abstract: Objectives: To improve the soil stability of Black Cotton (BC) soil which is abundantly found in East Godavari district and some costal areas of Andhra Pradesh in India as they are susceptible to detrimental volumetric changes, with changes in moisture. Methods: laboratory studies has been carried-out to investigate the influence of chemical called Terrabind on Balck Cotton (BC) soil from Amalapuram, East Godavari, Andhra Pradesh, and further the influence on BC when Terrabind is added in combination with Glass Powder (GP). Basic geotechnical properties like grain size distribution, specific gravity, consistency limits have been determined and engineering properties like Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Unconfined compressive strength, California Bearing Ratio (CBR), and Triaxial compression test have been determined for untreated and treated soil. Swelling properties have been determined by conducting free swell index test and swell pressure test. The laboratory investigations were conducted for different curing days to determine the basic and engineering properties of soil such as Atterberg’s limits, grain-size distribution, MDD, OMC, CBR, Unconfined Compressive Strength (UCS), Strength, Durability, Fatigue and Resilient Modulus (E). Findings: There is no huge soil expansion in the consistency limits for the compound (which compound) treated BC soil. Untreated soil shows LL=63%, PL =32%, and PI =34%. For soil settled with Terrabind, PI has diminished from 28% for one day restoring to 24% for 28 days relieving period. For soil balanced out with Terrabind+GP, PI has diminished from 27 % for one day restoring to 18% for 28 days relieving period. Improvement in dry density of treated soil is peripheral. MDD expanded from 17.6 KN/m3 to 18.4 KN/m3 and 18.7 KN/m3, and OMC was decreased from 16.32% to 16.24% and 16.12% for soil settled with Terrabind and Terrabind + GP for 28 days restoring period individually. Swell strain test results showed that Swell tension diminished from 49.5 KN/m2 to 36.73 KN/m2 and 35.12 KN/m2 for soil settled with Terrabind and Terrabind+ GP tried following 7 days of restoring. Swell tension was decreased by 26% and 29% for soil settled with Terrabind and Terrabind+ GP individually. Novelty: Soil stabilized with Terrabind and GP has showed better results compared to soil stabilized with Terrabind. Percentage weight loss was less than 14% for 12th cycle of freeze- thaw, which shows that the stabilized soil has become durable. Swelling has reduced to a great extent. The swelling of soil stabilized with Terrabind and Glass Powder (GP) has reduced by 100%
