1.1 This test method covers the determination of relative
density (specific gravity) and the absorption of coarse aggre-
gates. The relative density (specific gravity), a dimensionless
quantity, is expressed as oven-dry (OD), saturated-surface-dry
(SSD), or as apparent relative density (apparent specific
gravity). The OD relative density is determined after drying the
aggregate. The SSD relative density and absorption are deter-
mined after soaking the aggregate in water for a prescribed
duration.
1.2 This test method is not intended to be used with
lightweight aggregates that comply with Specification C332
Group I aggregates.
1.3 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.4 The text of this test method references notes and
footnotes that provide explanatory material. These notes and
footnotes (excluding those in tables and figures) shall not be
considered as requirements of this test method.
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 appro-
priate safety, health, and environmental practices and deter-
mine the applicability of regulatory limitations prior to use.
1.6 This standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
