About this material: #57 Crushed Stone (¾" – 1") →

How much does a ton of crushed stone cover?

Cubic yards = area (sq ft) × depth (in) ÷ 12 ÷ 27. Tons = cubic yards × the material’s density. The calculator then adds the buffer for compaction and spreading and rounds up. Tons use our catalog densities: #57 stone 1.35 t/yd³; #67 stone 1.35 t/yd³; stone dust 1.35 t/yd³; #4 crushed stone 1.25 t/yd³.

Crushed stone mistakes to avoid

Wrong stone size for the job

#57 is too coarse for a walking path and too small to be effective rip-rap. Match the gradation to the application: see the size guide below.

Skipping the base layer

A driveway needs 4 inches of base + 4 inches of top. A French drain needs filter fabric under and over the stone. Single-layer installs all fail prematurely.

Mistaking gravel for crushed stone

Rounded river gravel and crushed stone look similar but behave very differently. Crushed stone interlocks. Rounded gravel migrates.

Ignoring fines

Crusher run includes fines that pack hard but choke drainage. Use crusher run for base, washed #57 for drainage. Do not mix the two.
