2019-12-3 Specific Gravity is defined as the ratio of Weight of Aggregate to the Weight of equal Volume of water. The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Aggregates having low specific gravity are generally weaker than those with high specific gravity.

2018-10-30 1.1 This test method covers the determination of specific gravity and absorption of coarse aggregate. The specific gravity may be expressed as bulk oven dry (OD) specific gravity, bulk saturated surface dry (SSD) specific gravity, or apparent specific gravity. The bulk (SSD) specific gravity and absorption are based on aggregate after 15 to 19 hours soaking in water. This method is not intended to be used with lightweight aggregate.

2017-1-12 3.1 Bulk specific gravity is the characteristics generally used for calculation of the volumeoccupied by the aggregate in various mixtures containing aggregate including portlandcement concrete, bituminous concrete, and other mixtures that are porportioned oranalyzed on an absolute volume basis. Bulk specific gravity is also used in the computationof voids in aggregate in AASHTO T 19 and the determination of moisture in aggregate bydisplacement in water in AASHTO T 142. Bulk specific gravity determined on the saturatedsurface-dry basis is used if the aggregate is wet, that is, if its absorption has been satisfied.Conversely, the bulk specific gravity
