According to one aspect, a recycled asphalt shingle pellet can include a core including a recycled asphalt shingle waste and a softening agent; and a shell including no greater than 5% recycled asphalt shingle waste. The recycled asphalt shingle pellets can be a part of a batch of recycled asphalt shingle pellets having a large fiberglass sieve factor, F, of at least 98.2 wt. %. The batch can also have a small fiberglass sieve factor, F, of at least 99.1 wt. %.

Recycled asphalt pellet with reduced airborne fiberglass

Recycled asphalt shingle pellets having a core pellet, which includes recycled asphalt shingle waste with a softening agent, and a shell coating, which includes a binder with an aggregate blend of virgin recycled asphalt shingle waste and hydrated lime.

Compositions and methods for pelletized recycled asphalt shingles

Embodiments are directed to recycled asphalt shingle pellets having a soft center with a biofuel or bio-oil diluent, and a harder, water-resistant shell coating. It is believed that by using a biofuel, more recycled asphalt shingles material may be used in the formulation of asphalt cement without compromising the performance grade of the asphalt cement.
