Coarse Aggregate Specific Gravity | Pavement InteractiveSpecific gravity is a measure of a material's density (mass per unit volume) as compared to the density of water at 73.4°F (23°C). Therefore, by definition, water at a temperature of 73.4°F (23°C) has a specific gravity of 1. Absorption, which is also determined by the same test procedure, is a measure of the amount of water.mass determination in aggregates process,5.9.05 UNIT WEIGHT OF AGGREGATE - KDOTMay 9, 2005 . KT-5 reflects testing procedures found in AASHTO T 19. NOTE: Unit weight is the traditional terminology used to describe the property determined by this test method. Some believe the proper term is unit mass or density or bulk density, but consensus on this alternate terminology has not been obtained. 2.
