ASTM D5106-22

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.
Designation: D5106 − 15 D5106 − 22
Standard Specification for
Steel Slag Aggregates for BituminousAsphalt Paving
Mixtures
This standard is issued under the fixed designation D5106; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminousasphalt 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 D692D692/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 a bituminousan 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.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 steel slag, n—the nonmetallic product, consisting essentially of calcium silicates and ferrites combined with fused and
mineralogically combined oxides of iron, aluminum, manganese, calcium, and magnesium, that is developed simultaneously with
steel in basic oxygen, electric, or open hearth furnaces.
3.1.2 Other terms used in this specification are defined in Terminologies C125 and D8.
3.1 For definitions of terms used in this specification, refer to Terminologies C125 and D8.
4. Ordering Information
4.1 Orders for the material under this specification shall include the following information:
4.1.1 The name of material (steel slag coarse aggregate and/or steel slag fine aggregate).
4.1.2 The specification designation and year of issue.
4.1.3 The grading of the aggregate to be furnished, by reference to a size number in Classification D448 for coarse aggregate,
grading number in Specification D1073 for fine aggregate, or other grading as specified by the purchaser.
4.1.4 The quantity required.
4.1.5 For coarse aggregate, whether the intended use is for conventional mixtures or open-graded friction course mixtures (see
6.1.2), and whether for surface courses or base courses (see 6.1.3).

foreign materials such as clay, loam, wood, tramp metal, unhydrated lime, or other deleterious materials.
6. Physical Requirements
6.1 Coarse Aggregate:
6.1.1 Grading—The coarse aggregate grading shall conform to the requirements of Classification D448 for the size number
designated, or to another grading as stated in the order (Note 3).
NOTE 3—The coarse aggregate grading to be furnished is dependent upon the desired composition of the paving mixture,mixture and whether the grading
to be used in the mixture is achieved with or without blending. Other coarse aggregate gradings may be used provided that the combined aggregates and
filler, when used, will produce a paving mixture that provides the desired characteristics.
6.1.1.1 The size to be used is dependent upon the desired composition of the paving mixture,mixture and the required size or sizes
either before or after blending as specified.
