Tons of Crushed Stone per 100 Feet of 14 ft Road

Tons of crushed stone per 100 feet of 14 foot road: about 24 tons at 4 inches deep. The strip is 14 ft × 100 ft = 1,400 square feet. On a job this long, half an inch of extra depth adds a lot of tons.

The math

  1. Area: 14 × 100 = 1,400 sq ft.
  2. Volume at 4 in: 1,400 × 0.333 = 467 cu ft (17 cubic yards).
  3. × 1.4 tons per yard = 24 tons.

Road section basics

A 14-foot width fits one lane of traffic. 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

Works well for:

  • Driveway top courses and parking pads
  • Shed and hot tub bases
  • Backfill behind walls when a clean size is used

Poor fit 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 20x25 area at 2 inches takes about 4.3 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Mistakes that throw off the order

  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
