Standard Practice for Reclamation of Recycled Aggregate Base (RAB) Material

Significance and Use

4.1 Use of recycled aggregate base has become commonplace in transportation applications.

4.2 RAB may be used alone or in mixtures with other aggregate materials (virgin and/or recycled) in the production of unbound base course materials.

4.3 Quality of RAB is critical for successful reuse in pavement base applications. This practice is intended to provide a common baseline framework for assuring material, operator, and facility quality for production of RAB.

Scope

1.1 This practice covers selected aspects for reclamation of recycled aggregate base (RAB) material derived from asphalt pavement or concrete. RAB may be called recycled asphalt pavement (RAP) or recycled concrete aggregate (RCA).

1.2 This practice is provided related to material quality, material quality control testing, 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.
