For aggregates, density is determined by multiplying the relative density (specific gravity) of the aggregate times the density of water. Bulk Density of Aggregate [1] The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that is required to fill a container of a specified unit volume. Bulk Density = Mass / volume
