How the math works

  1. Area: 24 ft × 24 ft = 576 sq ft
  2. Volume @ 4": 576 × (4 ÷ 12) = 192.00 cu ft
  3. Add 10%: 192.00 × 1.10 = 211.20 cu ft
  4. Cubic yards: 211.20 ÷ 27 = 7.82 yd³
  5. Tons: 7.82 × 1.4 = 10.95 tons
  6. Truck loads: 27.38 tons ÷ 15 tons per tandem = 2

Trade pro tips

  • At 4" deep, 24x24 takes 10.95 tons — a single dump truck delivery covers it.
  • Build in layers: 4" of #3 (2"–3") stone, 4" of #57, then 2" of crusher run / dense grade on top.
  • Lay non-woven geotextile over clay soil first — it stops stone from sinking.
  • Crown the driveway ½" per foot so water sheds to the sides.
  • Spread with a box blade and compact each layer before the next.
