The math for a 10x75 driveway

  1. Area: 10 × 75 = 750 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 750 × 0.333 = 250.0 cu ft.
  4. Cubic yards: ÷ 27 = 9.26 yd³.
  5. Tons: × 1.3 = 12.0 tons.

About asphalt millings

Asphalt millings are ground-up old pavement. When compacted and warmed by sun they bind into a fairly firm surface, which is why they are popular for rural drives and lots. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

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. Since the driveway carries car and truck traffic, a little extra depth is cheap insurance.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 13.2 tons fits in a single 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 asphalt millings

Good uses:

  • Rural driveways and farm lanes
  • Parking areas where a dust-free surface is wanted
  • Low-cost base under a future paved surface

Think twice for:

  • Areas near wells or streams where local rules limit them
  • Decorative or barefoot areas
  • Jobs needing a uniform, clean look

Quick reference numbers

  • Per inch over 100 sq ft: about 0.40 tons of asphalt millings (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.0 tons.
  • Another size for comparison: a 10x20 area at 4 inches takes about 3.2 tons.
  • Weight used here: about 1.3 tons per cubic yard.

Common estimating mistakes

  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • 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.
