Tons of Crushed Stone per Mile of 18 ft Road
Tons of crushed stone per mile of 18 foot road: about 1,643 tons at 4 inches deep. The strip is 18 ft × 5,280 ft = 95,040 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 | 1,232 | 88 |
| 4 in | 1,643 | 118 |
| 6 in | 2,464 | 176 |
| 8 in | 3,285 | 235 |
The math
- Area: 18 × 5,280 = 95,040 sq ft.
- Volume at 4 in: 95,040 × 0.333 = 31,680 cu ft (1,173 cubic yards).
- × 1.4 tons per yard = 1,643 tons.
Road section basics
At 18 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.

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
Less suited to:
- 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 14x28 area at 3 inches takes about 5.1 tons.
- Weight used here: about 1.4 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.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
