    1. Scope

    1.1 This guide provides general information about possible types of permits, regulations, permits, and/or licenses, practices for stockpiling asphalt roofing shingle waste which may be needed prior to processing (grinding), deleterious materials and asbestos content testing, grinding waste shingles for use in asphalt mixtures, stockpiling RAS, obtaining RAS samples for quality control testing, and recommendations for basic quality control testing for RAS. 1.2. This guide does not include information or recommendations for evaluating RAS material properties such as RAS specific gravity, RAS asphalt content, and RAS asphalt binder properties which are typically used for designing asphalt mixtures. 1.3. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Useful practices for stockpiling recycled materials are needed so that these materials can be more uniformly stockpiled and processed. Improved uniformity is needed so that the variability of the final asphalt mixture can be reduced. Uniform terminology which can be used to indicate the general uniformity of the material in the stockpile and how the stockpile, once built, is maintained is needed to minimize confusion between users and producers when requirements for managing and maintaining supplies of recycled materials. While quality control testing varies considerably between agencies and commercial users, some general guidance is needed for what test method(s) are most useful for defining key recycled material properties. These key properties are needed for asphalt mixture sample preparation, design volumetrics, and asphalt mixture performance testing inputs.
