This recommended practice provides guidance for designing asphalt mixtures that incorporate reclaimed asphalt shingles (RAS) from manufactured waste or tear-off sources. Specific guidance includes design considerations, how to determine the shingle aggregate gradation, and how to determine binder quantity requirements for effective asphalt and binder quality requirements for binder embrittlement.
