Abstract
This study explores the upcycling of olive pomace as a sustainable antioxidant and recycling agent in asphalt paving materials. The olive pomace was processed to modify an asphalt binder and the optimal olive pomace percentage was determined. The performance tests were conducted to evaluate antioxidant performance and resistance to cracking and rutting of asphalt binders and mixtures. The results showed that pomace-modified asphalt binders had better resistance to oxidation-induced cracking and comparable rutting resistance when compared with the control binder. The pomace-modified asphalt mixtures exhibited better antioxidant and cracking performance than the control mixture.
