Tons of Crushed Stone per Mile of 16 ft Road
Tons of crushed stone per mile of 16 foot road: about 1,460 tons at 4 inches deep. The strip is 16 ft × 5,280 ft = 84,480 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 | 1,095 | 79 |
| 4 in | 1,460 | 105 |
| 6 in | 2,190 | 157 |
| 8 in | 2,920 | 209 |
The math
- Area: 16 × 5,280 = 84,480 sq ft.
- Volume at 4 in: 84,480 × 0.333 = 28,160 cu ft (1,043 cubic yards).
- × 1.4 tons per yard = 1,460 tons.
Road section basics
At 16 feet wide, two cars can meet with care. 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.

When to choose crushed stone
Good uses:
- 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 15x30 area at 3 inches takes about 5.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- 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.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
