Enhancing The Sustainability And Performance Of Bituminous Concrete Using Ceramic Waste And Copper Slag Additives

This study investigates the use of ceramic dust and copper slag as partial replacements in bituminous concrete to enhance performance and sustainability. Marshall Stability tests were conducted on traditional bituminous concrete with VG-30 bitumen in varying proportions (4%, 5%, 6%, 7%, and 8%), identifying 6% as the optimal content. Further tests with ceramic dust (5%, 10%, 15%, 20%, 25%) and copper slag (10%, 20%, 30%, 40%) found 10% ceramic dust and 20% copper slag to perform best individually. The combination of 10% ceramic dust and 20% copper slag showed the highest stability, improved strength, and better moisture resistance. This approach not only enhances pavement performance but also promotes environmental sustainability by repurposing industrial waste.
