Standard Specification for Steel Slag Aggregates for Asphalt Paving Mixtures

ABSTRACT
This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminous paving mixtures. The coarse and fine aggregates shall consist of hard, tough, durable pieces of steel slag, and shall be processed, as necessary, by crushing or screening, or both, and magnetic separation for the removal of metallics. At the time of delivery, the aggregates shall not contain injurious amounts of foreign materials such as clay, loam, wood, tramp metal, unhydrated lime, or other deleterious materials. The physical requirements for which the aggregates shall be tested on and consequently conform to are grading and fineness modulus, polishing characteristics, soundness, degradation, expansion, friable particles, stripping, adherent coatings, crushed count, plasticity index, leaching; and environmental stability.
SCOPE
1.1 This specification covers crushed steel slag coarse and fine aggregates suitable for use in asphalt paving mixtures.  
1.2 Steel slag coarse and fine aggregates are currently being used entirely (Note 1) or combined with other mineral aggregates, such as those covered in Specification D692/D692M or D1073, to produce paving mixtures similar to those described in Specification D3515 or D4215.
Note 1: When 100 % of the coarse aggregate in an asphalt mixture is steel slag, the amount of steel slag fines in that mixture may be limited to prevent bulking.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Note 2: 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 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
