How we calculate this

Crusher run is a mix of crushed stone and stone dust that compacts tightly, making it a popular driveway base material. It's denser than most gravel — around 2,800 lbs per cubic yard — so the same volume weighs more than looser materials like pea gravel.

Example

A 20 ft × 10 ft driveway base at 4 inches deep needs about 2.47 cubic yards of crusher run, roughly 3.5 tons before waste.

Common mistakes

  • Not compacting crusher run in layers, which can leave it uneven after settling.
  • Using a lighter-material density assumption, which underestimates the tonnage needed.

Frequently asked questions

What is crusher run used for?

Crusher run is commonly used as a compacted base layer under driveways, patios, and roads because it locks together well when compacted.

How is crusher run different from regular gravel?

Crusher run includes stone dust and fines along with crushed stone, which helps it compact into a dense, stable base — see our full Gravel & Rock Calculator for other material types.
