Granular A Gravel | 3/4 Minus Gravel | ASTM D2940
Granular A, A Gravel, or 3/4 inch minus is a mixture of sand and crushed gravel or rock. With mechanical compaction and reaching 98% standard Proctor Density, this material provides adequate stability and load support for paver bases. Through this compaction and with the loads that the base will bear, the coarse aggregate should not degrade.

Road Base Calculator
You will get this result if you estimate 1,430 kg/m³ as the gravel density. Since you already know the volume, use the equation d=m/V, where d is density, m is mass, and V is volume. Don't forget to use the same units and remember that 1 cubic yard = 0.76 m³. d = m / V m = d × V m = 1,430 kg/m³ × 0.76 m³ m = 1.09 ton
Introduction of Density of Aggregate
The density of aggregate is usually measured in kilograms per cubic meter (kg/m3) or pounds per cubic foot (lb/ft3). The density of aggregate varies depending on the type of aggregate used. Generally, the heavier the aggregate, the higher its density. For example, materials like crushed stone and gravel have a higher density compared to ...
