How many tons of gravel in a cubic yard?

Pea gravel ~1.4, crushed stone ~1.5, and #57 base ~1.7 tons per cubic yard.

What gravel is best for driveways?

A 4-inch base of #57 (crushed stone) topped with 2 inches of decorative gravel is the gold standard for residential driveways.

How deep should gravel be?

Paths and patios: 2 inches. Driveways: 4 inches base + 2 inches top. Drainage trenches: 6 inches or deeper.
