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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminous 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 D 692 or D 1073, to produce paving mixtures similar to those described in Specification D 3515 or D 4215.

Note 1—When 100 % of the coarse aggregate in a bituminous 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. The values shown in parentheses are for information only.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
