Asphalt Shingle Grinding Peterson
Asphalt Shingle Grinding (ASG) is the process of making Recycled Asphalt Shingles (RAS). RAS is produced by grinding asphalt roofing shingles to a small spec, generally under 3/8 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.
