This thesis presents the summary of several case studies on the long term performance of high recycled asphalt pavement (RAP) sections. Roadway sections which contained more than 20% RAP and that had been in place for at least 10 years were identified from across the United States and Canada with the help of the local agencies. The long term performances of these various recycled sections were compared directly to mixes made with similar virgin materials via measurements of distress criteria. These distress criteria included rutting, cracking, ride quality, and any overall performance rating that the local agencies used in evaluating their pavement sections. It was also insured that RAP and virgin sections were placed in the same general [...]
