Tons by thickness

Thickness	Tons	Tons +5%
1.5 in	15.4	16.2
2 in	20.5	21.6
2.5 in	25.7	27.0
3 in	30.8	32.4
4 in	41.1	43.1

How the numbers are built

1,700 sq ft × (2 ÷ 12) ft = 283 cubic feet at 2 inches.
× 145 lb = 41,083 lb.
÷ 2,000 = 20.5 tons.

Rule of thumb: roughly 6 tons per 1,000 square feet for every inch of thickness. 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. Overlays often run 1.5 to 2 inches; new work 2 to 3 inches.

Trucks and ordering

At 3 inches, 30.8 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.

When to choose asphalt

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 20x25 area at 2 inches takes about 6.2 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.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
