Repurposing of Coal Waste – Incorporation of Coal Waste in Asphalt Mixes
COALTECH Project Number: P2024-2
By Council for Scientific and Industrial Research | December 2025
Description
Coal waste, including fines and fly ash, can be safely and effectively incorporated into asphalt mixes without compromising mechanical or environmental performance. Asphalt containing coal waste demonstrates comparable or improved strength, durability, and resistance to moisture damage, while delivering cost and sustainability benefits. This approach supports circular economy principles by reducing waste, lowering reliance on natural aggregates, and improving material efficiency in road construction.
