24/07/2019 In this paper, the possibility of using different amounts of re-recycled (repeated recycled) Reclaimed Asphalt Pavement (RAP) in the asphalt mixture was experimentally investigated. First, a single virgin mixture was prepared and artificially aged to simulate the first generation of RAP to be used for designing the first generation of recycled mixtures. Next,

reclaimed asphalt pavement (RAP) binder properties and the amount of RAP in the mixture. Kiggundu et al w showed that mixtures prepared from the recycled binder blends generally age at a slower rate than virgin mixtures. This may be due to the fact that the RAP binder has already undergone oxidation which tends to retard the rate of hardening (4, 6) Kiggundu and Newman
