What is Specific Gravity of Coarse Aggregate about?
This test method determines the specific gravity and absorption of coarse aggregates through four determinations: bulk specific gravity, bulk saturated surface dry (SSD) specific gravity, apparent specific gravity, and percent absorption. The sample is oven-dried, immersed in water for 15 hours to achieve SSD, weighed in air and water to calculate specific gravities, and weighed again after drying to determine absorption. Specific gravity indicates quality and performance of aggregates for uses like asphalt
