This table is a data information resource for the specific gravity of many common general materials. While the data is extremely useful for design, actual individual samples will probably differ.
Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1.

B. Ballast/walkway aggregate shall be crushed stone broken by the crusher and have at least 2 broken surfaces: angular, rough-surfaced, clean and free of sand, loam, clay, flat, elongated, soft or disintegrated pieces, and other
The weight of crushed rock will vary greatly depending on the type of the stone and the size and uniformity of the crush. The smaller the crush size, the heavier the load. Solid rock is estimated at 2.5 to 3 tonnes per cubic metre. If rock is crushed into uniform sizes, the presence of open space
baker-weight of crushed stone cubic foot or a cubic yard of the solid stone, or its specific grav- ity, can be multiplied to give the weight per cubic yard of crushed
4.4 Mechanical Properties of Aggregates 4.4.1 Bond of Aggregate • Bond is the interlocking of the aggregate and the paste owing to the roughness of the surface of the former.
The weight of gravel per cubic yard is approximately 2,970 pounds, or 1.48 tons, if the gravel is dry. If the gravel is out of water, the weight per cubic yard is approximately 1,620 pounds or .81 tons.
Stone, crushed weighs 1.602 gram per cubic centimeter or 1 602 kilogram per cubic meter, i.e. its density is equal to 1 602 kg/m³. In Imperial or US customary measurement system, the Stone, crushed density is equal to 100 pound per cubic foot [lb/ft³], or 0.926 ounce per cubic inch [oz/inch³] .
As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.
