Abstract: The utilization of recycled waste materials in geotechnical and civil engineering presents an eco-friendly approach to waste management, with the potential to enhance soil properties. Scrap tyres, in particular, possess valuable characteristics that can be effectively harnessed for various engineering applications. This study conducted in sector H-12, Islamabad, Pakistan,examines the impact of incorporating crumb rubber, obtained from scrap tyres, as an additive in clayey soil. Soil specimens were statically compacted at optimum moisture content and maximum dry density, incorporating 3%, 5%, 7%, 10%, and 15% by weight of crumb rubber into the base soil. The experimental results indicate a reduction in optimum moisture content and maximum dry density. The California Bearing Ratio (CBR) strength demonstrated an initial increase with up to 7% rubber incorporation, followed by a subsequent decline. These findings suggest that waste crumb rubber can be effectively employed in various geotechnical applications up to a certain proportion, offering a sustainable solution for waste management and soil enhancement.
