Relative Density (Specific Gravity) and Absorption of ...

This test method covers the determination of relative density (specific gravity) and the absorption of coarse aggregate. The relative density (specific gravity), a dimensionless quantity, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or as relative density (apparent specific gravity). The OD relative density is determined after drying the aggregate.
