Abstract
To enhance the mechanical properties of problematic black cotton soil, engineers are focusing on reinforcing the soil with geosynthetic materials. This attention is particularly directed towards improving the strength characteristics of black cotton soil, given its inherent challenges associated with volume changes and plasticity. In this comprehensive study, red stone dust waste is introduced in varying percentages ranging from 5% to 35% to stabilize the black cotton soil. The goal is to assess the impact of different proportions of red stone dust on the stabilization of the soil. Furthermore, to augment the stability of the soil, polymer fabric is strategically incorporated at different depths, both in single and double layers. The California Bearing Ratio (CBR) tests are conducted on blends of black cotton soil and red stone dust, with the polymer fabric positioned at depths of H/3 and 2H/3 from the top of the loading surface. The results indicate that the blend containing 25% red stone dust yields the most favorable outcomes in terms of CBR improvement. Additionally, it is observed that the enhancement in CBR values is more pronounced when the reinforcement is applied in a single layer compared to double layers .In summary, the study reveals that the combination of red stone dust and polymer fabric reinforcement offers a promising approach for effectively stabilizing black cotton soil, with the optimal percentage of red stone dust and the configuration of the reinforcement layers playing crucial roles in achieving improved CBR values
