How much crusher run for a 24x20 parking pad is a quick volume problem. 480 square feet at 4 inches comes to 5.93 cubic yards. Crusher run usually weighs about 1.5 to 1.7 compacted tons per cubic yard, so plan on roughly 9.2 tons.
Volume and tonnage calculator →The math for a 24x20 parking pad
- Area: 24 × 20 = 480 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 480 × 0.333 = 160.0 cu ft.
- Cubic yards: ÷ 27 = 5.93 yd³.
- Tons: × 1.55 = 9.2 tons.
The volume and tonnage calculator does this for any size.
Crusher run needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 3 in | 4.44 | 6.9 | 7.6 |
| 4 in | 5.93 | 9.2 | 10.1 |
| 6 in | 8.89 | 13.8 | 15.2 |
| 8 in | 11.85 | 18.4 | 20.2 |
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. 10.1 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
Works well for:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Less suited to:
- 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 2 inches takes about 1.9 tons.
- Weight used here: about 1.55 tons per cubic yard.
Common estimating mistakes
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
