specific gravity 20 mm coarse aggregate

A Review of Aggregate and Asphalt Mixture Specific Gravity ...

BulkSpecific Gravity of Aggregate. Bulk specific gravity is defined as the ratio of the weight of a given volume of aggregate, including the permeable and impermeable voids in the particles, to the weight of an equal volume of water. Bulk specific gravity of aggregate is important information for designing HMA because it is used to calculate

Determining the specific gravities of coarse aggregates ...

Determining the specific gravities of coarse aggregates utilizing vacuum saturation approach. In lieu of the conventional soaking period of 24 ± 4 h, this proposed research approach employs the use of 10, 20 and 30 min of vacuum saturation at 30 mm Hg ( kPa) pressure. In this paper, the soaking time is 24 ± 4 h for all the AASHTO method.
