NAPA Publications: RAP & RAS

The National Asphalt Pavement Association has released two new books that can help asphalt pavement mix producers, engineering consultants, and road owners make the most effective utilization of reclaimed asphalt pavement (RAP). http://store.asphaltpavement.org
 
Best Practices for RAP and RAS Management (Quality Improvement Publication 129) by Randy C. West, Ph.D., P.E., covers pavement milling, inventory management, processing, sampling, and testing of RAP and recycled asphalt shingles (RAS), as well as a discussion of production concerns.
 
High RAP Asphalt Pavements: Japan Practice — Lessons Learned (Information Series 139) by Randy C. West, Ph.D., P.E., and Audrey Copeland, Ph.D., P.E., reports out the findings of a 2014 industry scanning tour of Japan to study that country’s use of high levels of RAP in its pavements. Information about Japanese innovations for porous asphalt pavements are also included.
 
Both publications were produced under NAPA’s cooperative agreement with the Federal Highway Administration (FHWA) and are available as free, high-quality PDF electronic documents through the NAPA Online Store.
