AASHTO MP 15:09(2011) Standard Specification for Use of Reclaimed Asphalt Shingles as an Additive in Hot Mix Asphalt (HMA). This specification covers reclaimed asphalt shingle material used as an additive in hot mix asphalt (HMA). The use of reclaimed asphalt shingles in hot-in-place pavements, cold-in-place pavements, and cold recycled pavements is not included in this specification. The values stated in Si units are to be regarded as the standard. Note 1—Refer to PP 53 for information on mix design. determining shingle aggregate gradation. and binder considerations when designing HMA mixtures that incorporate reclaimed asphalt shingles as an additive. 2.
