ASTM D5106−15 Standard Specification for Steel Slag Aggregates for Bituminous Paving Mixtures

ASTM D5106−15 Standard Specification for Steel Slag Aggregates for Bituminous Paving Mixtures

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 D692 or D1073, to produce paving mixtures similar to those described in Specification D3515 or D4215.

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. 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.

General Characteristics
5.1 The coarse and fine aggregates shall consist of hard, tough, durable pieces of steel slag as defined in 3.1.1.

The aggregates shall be processed, as necessary to meet the requirements of this specification, 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, Un hydrated lime, or other deleterious materials.
