Tons of Crusher Run per Mile of 12 ft Road
Tons of crusher run per mile of 12 foot road: about 1,819 tons at 6 inches deep. The strip is 12 ft × 5,280 ft = 63,360 square feet. Shoulders, pullouts and turnarounds add to the total; measure them separately.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 909 | 65 |
| 4 in | 1,212 | 87 |
| 6 in | 1,819 | 130 |
| 8 in | 2,425 | 174 |
The math
- Area: 12 × 5,280 = 63,360 sq ft.
- Volume at 6 in: 63,360 × 0.500 = 31,680 cu ft (1,173 cubic yards).
- × 1.55 tons per yard = 1,819 tons.
Road section basics
A 12-foot width fits one lane of traffic. 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. Crown the surface so water sheds to ditches on both sides.
Practical notes
- Phasing. Large tonnages are delivered over days; schedule spreading and compaction to keep up with trucks.
- Waste. Allow 5 to 10 percent.
- Hauling. Distance from the quarry or plant often costs as much as the material on long jobs; see asphalt hauling cost per ton.

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
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 14x28 area at 3 inches takes about 5.6 tons.
- Weight used here: about 1.55 tons per cubic yard.
Common estimating mistakes
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
