Specific Gravity. The ratio of weight of oven dried aggregates maintained for 24 hours at a temperature of 100 to 110 0 C, to the weight of equal volume of water displaced by saturated dry surface aggregate is known as specific gravity of aggregates. Specific gravities are primarily of two types. Apparent specific gravity; Bulk specific gravity

specific gravity of dry aggregate
Coarse Aggregate Specific Gravity Pavement . In the apparent specific gravity calculation the mass of the SSD aggregate sample is replaced by the mass of the ovendry aggregate sample (A replaces B), which means that the water permeable voids within the aggregate are not included and (A – C) is the mass of water displaced by the ovendry sample.
