Abstract In this study Cyclogen, Rapiol and waste cooking oil was used as rejuvenators to improve properties of aged bitumen. The effects of these rejuvenators on asphalt mixtures containing 50% of reclaimed asphalt pavement specimens was evaluated using dynamic creep, resilient modulus, low temperature fracture energy and moisture susceptibility tests and the results was compared to recycled mixtures without rejuvenator and control HMA mixtures. The results showed that the rejuvenators are effective in alleviating the aging effect of RAP bitumen. Waste cooking oil performed better than other studied rejuvenators followed by Cyclogen and Rapiol. However, moisture resistance was impaired when rejuvenators were used.
