Guidelines for RAS Use Publication Updated

EVERY YEAR, ABOUT 13.2 million tons of asphalt roofing shingle waste is generated across the U.S.

The asphalt binder, aggregates, and fibers in waste shingles can be successfully used in new roads, parking lots, and other asphalt pavements.

To aid in the further use of waste asphalt shingles in asphalt pavements, NAPA released an updated version (https://goaspha.lt/IS136-2e) of Guidelines for the Use of Reclaimed Asphalt Shingles in Asphalt Pavements (IS 136), originally issued in 2009.

The publication covers sourcing of waste roofing shingles, inspection for contaminants, shingle processing, mixture design guidance, binder adjustments, and production and construction considerations. It also examines the sustainability and economic benefits of recycling asphalt shingles.
