1.1 This practice covers reclamation of asphalt shingles derived from manufacturing scrap and tear-off roofing. Reclaimed asphalt shingles (RAS) are used in roadway and other applications including asphalt paving materials and unbound materials such as granular fill. 1.2 Guidance is provided relating to material quality, material quality control, and also operator and facility qualifications. 1.3 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. Note 1: Sieve size is identified by its standard designation in Specification E11 . The alternative designation given in parentheses is for information only and does not represent a different standard sieve size. 1.4 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Use of reclaimed asphalt shingles in asphalt production has become commonplace in transportation applications. 4.2 Use of reclaimed asphalt shingles in unbound applications, such as granular fill, alone or in mixtures with other materials, is developing. 4.3 The quality of RAS is critical for successful reuse of the shingles in asphalt production and other unbound applications. Various specifications are used regarding RAS. 4.4 This practice provides a common baseline framework for assuring material, operator, and facility quality for RAS production. 4.5 This practice provides sourcing, inspecting, sampling, testing, and stockpiling requirements for RAS operators. 4.6 This practice includes a certification form that is used for quality control and quality assurance for the facility, operations, and incoming material and outgoing product.
