AASHTO PP 78-14 (2016)

This recommended practice provides guidance for designing asphalt mixtures that incorporates 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 the performance grade (PG) of the binder.

Note—Refer to AASHTO MP 23 for baseline information (source requirements, shingle gradation, and deleterious requirements) to consider when using RAS in asphalt mixtures.
