The National Asphalt Pavement Association (NAPA) produced two books, Best Practices for RAP and RAS Management and High RAP Asphalt Pavements: Japan Practice — Lessons Learned. They believe that these books will help "asphalt pavement mix producers, engineering consultants, and road owners make the most effective utilization of reclaimed asphalt pavement (RAP)."

According a NAPA survey, during the 201 construction season 75 million tons of recycled material were used to help create new asphalt pavement mixtures.

"Asphalt pavements are inherently sustainable, because when we pave a road, we put in place material that can later be harvested for reuse in new pavements," said Copeland. "These two publications will help road builders and road owners alike evaluate and increase the effectiveness of their utilization of RAP while ensuring pavement performance."
