The math for a 12x50 parking pad

  1. Area: 12 × 50 = 600 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 600 × 0.333 = 200.0 cu ft.
  4. Cubic yards: ÷ 27 = 7.41 yd³.
  5. Tons: × 1.55 = 11.5 tons.

About crusher run

Crusher run (also sold as crush and run, dense-grade aggregate or QP in some regions) mixes stone with stone dust. It compacts into a firm, nearly solid layer, which makes it the usual base under pavers, asphalt and gravel drives. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.

Preparing the parking pad

Dig out organic soil, compact the subgrade and set an edge so the stone does not migrate onto the lawn. A pad that holds parked weight for long periods benefits from a dense base under the surface stone. Since the parking pad carries parked vehicles, a little extra depth is cheap insurance.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 12.6 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
  • Bulk vs bags. At this size bulk delivery is usually the practical choice.
  • Where it drops. Have the truck dump as close to the parking pad as firm ground allows.

Where crusher run fits

Best suited to:

  • Base under asphalt, pavers or concrete
  • Gravel drives that need a firm, packed surface
  • Shed pads and equipment pads

Poor fit for:

  • Drainage layers, since the fines slow water
  • Decorative beds
  • Spots where you want water to soak straight through

Quick reference numbers

  • Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.8 tons.
  • Another size for comparison: a 10x20 area at 3 inches takes about 2.9 tons.
  • Weight used here: about 1.55 tons per cubic yard.

Mistakes that throw off the order

  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
