Abstract
 Aseries of laboratory tests were conducted to confirm the aging property of repetitive recycled asphalt and mixture. In this study, rejuvenator which consists of different component, and high penetration asphalt were applied to recycling procedure.
 As a result, the differences of the aging were occurred in physical and chemical properties of recycled asphalt mixture and recycled asphalt, according to difference in composition of rejuvenator. The rejuvenator, which composed of low saturates and high aromatics could constrain the aging of properties in recycled asphalt mixture and recycled asphalt.
