Guidelines for RAS Use Publication Updated

Guidelines for the Use of RAS in Asphalt Pavements, 2nd Edition Every year, about 13.2 million tons of asphalt roofing shingle waste is generated across the United States. This asphalt-rich material does not have to end up in landfills. Instead, the asphalt binder, aggregates, and fibers in waste shingles can be successfully put to use in new roads, parking lots, and other asphalt pavements. To aid in the further use of waste asphalt shingles in asphalt pavements, the National Asphalt Pavement Association (NAPA) has released an updated second edition of Guidelines for the Use of Reclaimed Asphalt Shingles in Asphalt Pavements (IS 136)

 

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 includes information on the sustainability and economic benefits of recycling asphalt shingles.
