Coarse Aggregate Specific Gravity – Pavement Interactive
Specific gravity is a measure of a material's density (mass per unit volume) as compared to the density of water at 73.4°F (23°C). Therefore, by definition, water at a temperature of 73.4°F (23°C) has a specific gravity of 1. ... (4.75 mm) sieve. This discards small aggregate particles clinging to the retained large particles.
