Tons by thickness

Thickness	Tons	Tons +5%
1.5 in	61.2	64.2
2 in	81.6	85.6
2.5 in	102.0	107.1
3 in	122.3	128.5
4 in	163.1	171.3

How the numbers are built

6,750 sq ft × (2 ÷ 12) ft = 1,125 cubic feet at 2 inches.
× 145 lb = 163,125 lb.
÷ 2,000 = 81.6 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.

How big 6,750 square feet is

This is commercial scale: a parking lot, a long private road or a large apron. The bigger the area, the more a small change in thickness swings the total tons.

Trucks and ordering

At 3 inches, 122.3 tons is about 10 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 4 inches takes about 12.3 tons.
Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).

Mistakes that throw off the order

Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
