Ziari et al. investigated the rutting resistance of recycled asphalt concrete containing 25, 50 and 75% of RAP and rejuvenated by a constant dose of waste cooking oil and found that the resistance against rutting decreases with adding rejuvenator. However, the reduction of rutting resistance can be compensated by adding nano-clay.

(4) Compared with the mineral oil-based rejuvenator, the vegetable oil-based rejuvenator is more favorable for recovering the fatigue resistance of aged asphalt. When the amount of waste edible vegetable oil-based rejuvenator is more than 8%, the fatigue resistance of recovered asphalt is even one grade higher than that of asphalt.

Abstract. This study investigates the chemical and morphological behavior of rejuvenated asphalt binders. A TFOT aged PG 58-28 binder was mixed with three different types of rejuvenators that include waste cooking oil/untreated used cooking oil (UT), treated used oil (TR), and Hydrolene (HL) at 3, 6, and 9% by the weight of the total binder.
