The math for a 14x80 driveway

  1. Area: 14 × 80 = 1,120 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 1,120 × 0.333 = 373.3 cu ft.
  4. Cubic yards: ÷ 27 = 13.83 yd³.
  5. Tons: × 1.4 = 19.4 tons.

About crushed stone

Most quarries sell crushed stone by a size number or a screen size. Clean crushed stone drains well; stone with fines packs harder but sheds water more slowly. Weight per yard is a planning number; the scale ticket at the yard is the real one.

Preparing the driveway

Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. For car and truck traffic, the depths in the table above are a reasonable starting range.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 21.3 tons may take more than one typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
  • Bulk vs bags. At this size bulk delivery is usually the practical choice.
  • Where it drops. Have the truck dump as close to the driveway as firm ground allows.

When to choose crushed stone

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 8x16 area at 4 inches takes about 2.2 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Where estimates go wrong

  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
