Tons by thickness

Thickness	Tons	Tons +5%
1.5 in	14.5	15.2

2.5 in	24.2	25.4
3 in	29.0	30.5
4 in	38.7	40.6

How the numbers are built

1,600 sq ft × (2 ÷ 12) ft = 267 cubic feet at 2 inches.
× 145 lb = 38,667 lb.
÷ 2,000 = 19.3 tons.

Quick check: about 0.006 tons per square foot per inch. See tons of asphalt per 1,000 square feet.

Putting the area in context

This is a large residential driveway or a small commercial lot. Most homeowners land between 2 and 3 inches compacted.

Trucks and ordering

At 3 inches, 29.0 tons is about 3 truckloads at around 14 tons each. Plants set minimum orders and charge for hauling; see asphalt hauling cost per ton.

Things that move the total

Mix density typically runs 140 to 150 lb per cubic foot.
Base condition: dips and ruts fill with extra mix.
Waste of 5 to 10 percent is a common allowance.

Where asphalt fits

Works well for:

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

Less suited to:

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 14x28 area at 4 inches takes about 9.7 tons.
Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).

Where estimates go wrong

Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
