The recycling of asphalt pavements has become a very routine procedure throughout the country. Research has shown that the recycled asphalt pavement (RAP) recovered from construction sites still contains usable materials, both in the recycled aggregates and recycled binder. The fatigue life and rut resistance of mixtures containing various amounts of recycled asphalt pavement (RAP) were compared with a virgin mixture. The fatigue life and rut resistance of the mixtures were calculated from laboratory testing using Frequency Sweep Testing using Superpave Simple Shear Tester (SST) and Repeated Simple Shear Tests using (SST) device. The SHRP A-003A surrogate models and the Asphalt Institute models were both be used in order to predict pavement performance using the results from the Frequency Sweep Testing and the Repeated Simple Shear Test.
