The math

  1. 45 tons × 2,000 = 90,000 lb.
  2. ÷ 145 lb per cu ft = 620.7 cu ft.
  3. ÷ (2 ÷ 12) ft = 3,724 sq ft at 2 inches.

What that area looks like

2,483 square feet is about a 49 by 49 foot square, or a 12-foot-wide strip about 207 feet long at 3 inches. That is a large drive or a small lot.

Things to keep in mind

  • Density varies from about 140 to 150 lb per cubic foot by mix.
  • Waste and base dips use 5 to 10 percent more.
  • Truck loads: 45 tons is about 4 typical tandem loads.

Good and poor uses for asphalt

Best suited to:

  • Driveways, parking pads and private lanes that need a smooth, sealed surface
  • Overlays on old pavement that is cracked but still structurally sound
  • Areas where snow will be plowed, since a paved surface does not throw stone

Poor fit for:

  • Ground that stays soft or wet, unless the base and drainage are fixed first
  • Very small patches, where bagged cold patch is often simpler
  • Jobs in cold weather, since hot mix needs warm temperatures to compact properly

Quick reference numbers

  • Per inch over 100 sq ft: about 0.62 tons of asphalt (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 6.2 tons.
  • Another size for comparison: a 12x24 area at 3 inches takes about 5.3 tons.
  • Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).

Common estimating mistakes

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