ASTM C127 15 Standard Test Method for Relative Density. Specific Gravity “It is the ratio of the density of the aggregate material to the density of the gas free distilled water at a standard temperature (i.e. 4oC)”. The relative density is a dimensionless quantity and is expressed as oven dried saturated surface dry and apparent specific gravities. 4.2.6., Bulk Density. Bulk density is defined by the ratio of the mass, m, of an amount of bulk solid to its volume, V.
