How deep should gravel be for a driveway?

4-6 inches for a gravel driveway. Use 4 inches of crushed stone base, then 2 inches of smaller gravel on top. For foot-traffic paths, 2-3 inches is sufficient.

How many tons is a cubic yard of gravel?

Approximately 1.35 tons per cubic yard for average gravel. This varies: pea gravel is about 1.3 tons/yd³, crushed limestone is 1.4, and river rock can be 1.5.

How much does gravel cost per ton?

$25-75 per ton depending on type and location. Delivery fees add $50-150. Pea gravel is cheapest, decorative stone is most expensive. Buying in bulk (10+ tons) often drops the per-ton price.
