Tons of Crusher Run per Mile of 32 ft Road
Tons of crusher run per mile of 32 foot road: about 4,850 tons at 6 inches deep. The strip is 32 ft × 5,280 ft = 168,960 square feet. Long runs magnify small depth changes, so pin the depth down before ordering.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 2,425 | 174 |
| 4 in | 3,233 | 231 |
| 6 in | 4,850 | 347 |
| 8 in | 6,466 | 462 |
The math
- Area: 32 × 5,280 = 168,960 sq ft.
- Volume at 6 in: 168,960 × 0.500 = 84,480 cu ft (3,129 cubic yards).
- × 1.55 tons per yard = 4,850 tons.
What goes into the section
A 32-foot width gives two full lanes. 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
Works well for:
- 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.
Where estimates go wrong
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
