Tons of Crushed Stone per Mile of 28 ft Road
Tons of crushed stone per mile of 28 foot road: about 2,555 tons at 4 inches deep. The strip is 28 ft × 5,280 ft = 147,840 square feet. On a job this long, half an inch of extra depth adds a lot of tons.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 1,916 | 137 |
| 4 in | 2,555 | 183 |
| 6 in | 3,833 | 274 |
| 8 in | 5,111 | 366 |
The math
- Area: 28 × 5,280 = 147,840 sq ft.
- Volume at 4 in: 147,840 × 0.333 = 49,280 cu ft (1,825 cubic yards).
- × 1.4 tons per yard = 2,555 tons.
Road section basics
A 28-foot width gives two full lanes. Crushed stone has fractured faces, so the pieces interlock when compacted. That is why it holds a driveway or pad shape better than round stone of the same size. 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 crushed stone fits
Best suited to:
- Driveway top courses and parking pads
- Shed and hot tub bases
- Backfill behind walls when a clean size is used
Think twice for:
- Barefoot areas, since angular stone is rough
- Play areas
- Places that need a smooth rolling surface for wheels
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 12x24 area at 4 inches takes about 5.0 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- 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.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
