Investigating the Creep and Fatigue Properties of Recycled Asphalt Concrete Containing Waste Engine and Waste Cooking Oil
This study attempts to investigate the viability of using waste engine oil (WEO) and waste cooking oil (WCO) as rejuvenator in asphalt concrete containing reclaimed asphalt pavement (RAP). Different percentages of the waste oils, namely 0, 5, 10 and 15% (by the weight of total binder) have been added into an asphalt concrete containing, 25, 50 and 75% of RAP and the effects on creep and fatigue properties have been investigated. The rutting resistance was found to increase with adding RAP, with lower increase for adding 50% RAP than 25 and 75%, and decrease with adding WEO and WCO, with lower decrease for adding 10% than adding 5 and 15%. Stress controlled fatigue tests showed that the fatigue resistance of non-rejuvenated mixtures grows with increasing RAP content, and, in general, the increase of WEO/WCO dosage results in the decrease of fatigue life. At the same dosage of rejuvenator, WEO results in more fatigue life than WCO, indicating that higher WEO is allowed to be used in recycled mixtures.
