Standard Practice for Design Considerations When Using Reclaimed Asphalt Shingles (RAS) in Asphalt Mixtures standard by American Association of State and Highway Transportation Officials, 2017
AASHTO PP 78-17 (2020) 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 1 – Refer to MP 23 for baseline information (source requirements, shingle gradation, and deleterious requirements) to consider when using RAS in asphalt mixtures.
