Phạm vi áp dụng / Scope of standard

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.

Note 1-Refer to MP 23 for baseline information (source requirements, shingle gradation, and deleterious requirements) to consider when using RAS in asphalt mixtures.
