One way to be developed to overcome challenges in providing flexible pavement materials is to apply the principle of green roads by reusing some or all of the old road pavement material or Reclaimed Asphalt Pavement (RAP) as a material for new road pavement, which if reused will affect the performance of the mixture. Such as decreasing the level of durability and premature pavement damage, so an effort must be made to improve the performance of the recycled material, namely by rejuvenating materials. The RAP material is obtained from scratching the asphalt of the Jakarta-Cikampek Toll Road. The mixture used is asphalt concrete Wearing Course AC-WC using 20%, 25%, and 30% RAP material with te use of Iterlene rejuvenating agent of 5%. Then Marshall tested the mixture with RAP material, Resilience modulus with UTM, and resistance to fatigue four-point loading test method with strain control. The use of RAP material and Pen 60/70 Asphalt using Iterlene rejuvenating agent can increase the stiffness of the asphalt. Marshall test results show a mixture 30% RAP material content gives the highest stability value. The results of the Resilience Modulus test show that the 0% RAP material content gives a high Resilience Modulus value at a test temperature of 45oC. The results of the fatigue resistance test showed that the mixture 30% RAP material content at 25°C gave the most extended fatigue life.
