Tons by thickness

Thickness	Tons	Tons +5%
1.5 in	56.6	59.5
2 in	75.5	79.3

How the numbers are built

6,250 sq ft × (2 ÷ 12) ft = 1,042 cubic feet at 2 inches.
× 145 lb = 151,042 lb.
÷ 2,000 = 75.5 tons.

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

What size job this is

This is commercial scale: a parking lot, a long private road or a large apron. Commercial lots usually call for thicker sections and a binder course under the surface.

Trucks and ordering

At 3 inches, 113.3 tons is about 9 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

Good uses:

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 10x20 area at 3 inches takes about 3.7 tons.
Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).

Mistakes that throw off the order

Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
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.
