Every year, millions of tons of asphalt shingles end up in landfills, presenting significant waste management issues. The Georgia Department of Transportation has launched trials to incorporate recycled shingle materials into asphalt mixes, discovering potential cost savings. Performance tests showed these mixes were comparable to traditional asphalt, despite some minor concerns. Other states have mirrored this effort, yielding diverse outcomes regarding durability.
