Abstract-Black cotton soil, renowned for its expansive characteristics and limited load-bearing capacity, poses significant hurdles in construction endeavors. When exposed to varying moisture levels, this soil type typically undergoes swelling and shrinking, showcasing weak mechanical properties. This study investigates into the potential of repurposing recycled Construction and Demolition (C&D) waste to stabilize black cotton soil. It examines the incorporation of diverse C&D waste materials—such as concrete, bricks, mortar, and other construction remnants—into black cotton soil to bolster its mechanical resilience and stability. The research evaluates the efficacy of blending C&D waste at varying percentages (5%, 10%, 15%, 20%, and 25%) to mitigate soil swelling, enhance strength, and improve load-bearing capacity. Parameters including plasticity index, optimum moisture content, maximum dry density, and differential free swell index are scrutinized concerning the integration of recycled C&D wastes for soil stabilization. Through comparative analysis, this study aims to offer valuable insights into sustainable methodologies for augmenting the performance of black cotton soil while minimizing construction-related waste generation.
