Bulk specific gravity determines the ratio of the weight of the sample to the ratio of an equal volume of water. It test measures a sample based on a certain condition. Given below is the simple Bulk specific gravity formula to determine the bulk specific gravity of coarse aggregate based on known values of weight of dry piece in a fluid, a density of a fluid, a weight of dry piece soaked in fluid and weight of dry piece soaked & immersed in a fluid.

Where,

G

W = Weight of Dry Piece in Fluid

D = Density of Fluid

S = Weight of Dry Piece Soaked in Fluid

I = Weight of Dry Piece Soaked & Immersed in Fluid

The bulk specific gravity of a bituminous mixture is the ratio of the weight of the compacted bituminous mixture sample to the bulk volume of the specimen. Use this Bulk specific gravity formula to do calculations on your own as per the operations demanded by the formula.
