Since November 2003, Rooftop has recycled approximately 61,000 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

Environmental issues

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

Cold Mix

Dust Control

A study showed that a blend with no fines had the greatest strength
