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. The SSD relative density and absorption are determined after soaking the aggregate in water for a prescribed duration.
WJE laboratories are accredited by AASHTO (R18) and ANAB (ISO/IEC 17025) to perform testing standard ASTM C127 for Relative Density (Specific Gravity) and Absorption of Coarse Aggregate.
