Best practice for using RAS in HMA

"The use of recycles asphalt shingles (RAS) in hot-mix asphalt (HMA) mixtures has the potential to significantly reduce the cost of asphalt paving mixes while conserving energy and preserving the environment. This report documents the best practices for the use of RAS in HMA in terms of Ras processing, characterizing the processed RAS (binder content,gradations, and performance grad [PG]), RAS mix design, production, and field construction."
