Americans discard about 15 million tons of asphalt roof shingles a year, but old roofs can be ground up and put straight back into the roads people drive on

Millions of tons of asphalt shingles are disposed of annually in the United States. These old roofing materials can be processed into recycled asphalt shingles for road construction. Research confirms that pavements containing recycled shingles can meet quality requirements. Proper processing and quality controls are essential for this material recovery. This recycling effort diverts waste and creates valuable road infrastructure components.
