πŸ’‘ How to Calculate Aggregate Quantities

Aggregate is the general term for crushed stone, gravel, road base, and similar materials used as sub-bases under concrete, asphalt, and pavers. Different aggregates have different densities: crushed stone weighs about 1.4 tons per cubic yard, road base (Class 5) about 1.6 tons, and pea gravel about 1.4 tons.

The calculation is straightforward: Length Γ— Width Γ— Depth = Volume in cubic feet, divide by 27 for cubic yards, then multiply by the material's density for tons. Sub-base depths vary by application: 4 inches for walkways, 6 inches under patios, and 8–12 inches under driveways.

A 20Γ—20 ft driveway sub-base at 6 inches of Class 5 road base: 200 cu ft = 7.4 cu yd Γ— 1.6 tons/yd = 11.9 tons. At $25 per ton, the material costs about $297.
