Coarse Aggregate Specific Gravity – Pavement Interactive

Apparent specific gravity is intended to only measure the specific gravity of the solid volume, therefore it will be the highest of the aggregate specific gravities. It is formally defined as the ratio of the mass of a unit volume of the impermeable portion of aggregate (does not include the permeable pores in aggregate) to the mass of an equal ...

2020-2-5  The specific gravity of an aggregate is defined as the ratio of the mass of the solid of a given volume of sample to the mass of an equal volume of gas-free distilled water, both taken at the standard temperature i.e. 27-degree celsius. Since the aggregate generally contains voids, there are different types of specific gravities.
