Since November 2003, Rooftop has recycled approximately tons of post-consumer asphalt roofing shingles.
Multiple state and local government plan approvals, permits and licenses required.
91 percent (by weight ??) of the mixed loads of roofing material is recyclable shingles. Other non-shingle recyclable materials include: wood and metal. Miscellaneous non-recyclable waste includes: contaminated plastic, other trash, etc.
Aggressive asbestos management program to comply with State of Massachusetts laws, rules and permit requirements:
Current uses include: HMA, cold patch, road base, and dust control
Future uses may include: new shingles, and fuel
Looking ahead to a potential landfill ban of recyclable shingles

Benefits to Recycling Shingles
Shingles composed of 20-40% liquid Asphalt Cement
Fiber & polymers from shingles can add strength to mix design
Can be added to HMA to offset liquid AC costs or to create new mixes
Problems to overcome:
Tear-offs: intensive pre-processing, contamination, mold concerns
Allocating space for equipment & covered or enclosed area’s for stockpiles
Crossing the economic barrier: sizing of final product is important
Products for RAS:
Hot Mix Asphalt
A study showed that a blend with no fines had the greatest strength
