as preconized by siddique (2010b), the bulk specific gravity values of the mswi ash ranges from 1.5 to 2.2 for the sand-size or fine particles and 1.9 and 2.4 for the coarse particles compared to approximately 2.6–2.8 for conventional aggregate materials.
bulk specific gravity of the fine aggregate is used in hot-mix asphalt volumetric-mix design (including superpave) to determine the amount of asphalt binder absorbed by the aggregate and the percentage of voids in the mineral aggregate. the current test method (aashto t84) uses a cone method to establish the saturated surface dry (ssd) condition of

(a) combined bulk (oven dry), bulk (ssd), or apparent specific gravity for coarse aggregate and fine aggregate is determined by the following: f f c c c f g p g p p p combined specific gravity + + = where: p c = percent of coarse aggregate p f = percent of fine aggregate p c + p f = 100 g c = specific gravity of coarse aggregate g f = specific gravity of fine aggregate
so apparent specific gravity is defined as the ratio of the mass of unit volume of impermeable portion of fine aggregate which does not includes permeable pore in fine aggregate to the mass of an equal volume of gas free distilled water at the stated temperature. what is bulk specific gravity. it is denoted by gsb.
bulk specific gravity is a measurement of the volume of the aggregate particle as well as the volume of the water permeable voids. the mass measurement only includes the aggregate particle. since it includes the water-permeable void volume, the bulk specific gravity will be less than apparent specific gravity. bulk saturated surface dry (ssd) specific gravity includes the overall volume of the aggregate
