    WK64272

    1. Scope

    1.1 This practice provides general information about potential regulations, initial stockpiling of reclaimed asphalt shingles (RAS), grinding of stockpiled materials, stockpiling ground RAS, sampling, quality control testing, and testing needed for asphalt mix designs. 1.2 Units--The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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.


    Keywords

    Rationale

    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 that 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.

    The title and scope are in draft form and are under development within this ASTM Committee.
