Most aggregates have a relative density between 2.4-2.9 with a corresponding particle density (Mass) of 2400-2900 kg / m3 (150-181 lb / ft3). Here, for coarse aggregates, the standard test method was explained in ASTM C 127 (AASHTO), and, for fine aggregates, the standard test method was explained in ASTM C 128 (AASHTO).

The aggregate produced in a primary crusher is classified using a screen into a 0-20 mm fraction and typically a 20-150 mm fraction. The 0-20 mm fraction contains soil etc. and is generally considered to be of poor quality. This fraction is often used in road construction applications that feature low quality requirements.

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)

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.

Now discuss density of aggregate in other units like lb/m3,g/cm3 and kN/m3. density of aggregate in lb/ft3:-we know that aggregate density is 1200 - 1750 kg/m3,converting it into lb/ft3 minimum = 1200×0.0624 =75 and maximum = 1750×0.0624 =109, so density of aggregate in lb/ft3 is ranging between 75 - 109.

Aggregate " is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent of HMA and about 70 to 80 percent of portland cement concrete.
