Abstract
Asphalt binder loses its properties due to oxidation and becomes stiffer over time. Restoring the properties of the aged asphalt binder is a major challenge to recycle asphalt pavement. Waste engine oil (WEO) and waste cooking oil (WCO) were used in this study as rejuvenators to restore the extracted aged binder properties. The physical and rheological properties of the rejuvenated aged binder were analysed, and optimum dosages were determined. Binder test results showed that the WEO and WCO effectively rejuvenated the extracted aged binder. The optimum dosages of WEO and WCO that returned the aged binder with penetration 11 dmm to its reference penetration value (58 dmm) were 18% and 12%, respectively. The rheological properties in terms of rutting resistance of the aged binder could also be regained to a normal level with different contents of WEO or WCO.
