Asphalt Shingle Grinding (ASG)


Asphalt Shingle Grinding (ASG) is the process of producing Recycled Asphalt Shingles (RAS) by processing asphalt roofing shingles to a small spec, generally under 3/8” (9.525 mm) to salvage the valuable asphalt and sand. Grinding asphalt shingles is a recycling effort which diverts materials from the landfill and can reduce road building costs.

Peterson’s ASG Breaker Grate is a type of anvil breaker grate used specifically for asphalt shingle grinding.
