Tons of Gravel per Mile of 28 ft Road

Tons of gravel 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. Shoulders, pullouts and turnarounds add to the total; measure them separately.

The math

  1. Area: 28 × 5,280 = 147,840 sq ft.
  2. Volume at 4 in: 147,840 × 0.333 = 49,280 cu ft (1,825 cubic yards).
  3. × 1.4 tons per yard = 2,555 tons.

Road section basics

A 28-foot width gives two full lanes. Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. 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.

Good and poor uses for gravel

Best suited to:

  • Rural driveways and lanes where low upfront cost matters
  • Drainage areas and around downspouts
  • Temporary access while a site is under construction

Poor fit for:

  • Steep slopes, where loose stone washes downhill
  • Spots plowed often, since plows push gravel into the lawn
  • Areas next to doors, because stone tracks inside

Quick reference numbers

  • Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.3 tons.
  • Another size for comparison: a 10x20 area at 2 inches takes about 1.7 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Where estimates go wrong

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
