How Many Square Yards Does a Ton of Asphalt Cover?

At 145 pounds per cubic foot, one ton of compacted hot mix covers about 18.4 square yards at one inch, about 9.2 at two inches, and about 6.1 at three inches. Square yards are square feet divided by nine. The plant ticket is the real weight.

Turn square feet into square yards

One square yard is a three-by-three block, which is 9 square feet. Coverage in square yards is the square-foot coverage divided by 9. At a planning density of 145 pounds per cubic foot, one ton is about 13.8 cubic feet, and that volume covers about 166 square feet at one inch. Divide 166 by 9 and you get about 18.4 square yards per ton at one inch. At two inches the ton covers about half of that, near 9.2 square yards. At three inches it covers about 6.1 square yards. You can also take about 18.4 and divide by the thickness in inches. The two routes should land in the same place. Keep the thickness in the sentence every time you quote a coverage, or a square-yard bid and a square-foot sketch will not describe the same pavement.

Why the bid unit and the sketch must share a thickness

Commercial proposals are often written in square yards, while a homeowner tape is usually in feet. The tons will match only when both sides use the same compacted thickness. A bid for 200 square yards at two inches is not the same material quantity as 200 square yards at three inches. Convert first if you must: multiply square yards by 9 to get square feet, then run the ton formula. Tons equal square feet times inches divided by 12, times 145, divided by 2,000. Label the result a planning estimate. The plant ticket is the real weight. If one person measured the apron in feet and another priced the job in yards, divide or multiply by 9 before you argue about the load. Skipping that step makes a correct thickness look like a bad scale.

What the yard coverage leaves out

Square-yard math assumes a uniform compacted depth. It does not add the extra mix a crew rakes along a gutter, a flare, or a post. It also assumes the planning density, not whatever number your plant prints for a particular mix. A heavier mix covers fewer square yards per ton. A lighter open mix covers more, and you should not paste 18.4 onto that product. After the pour, divide ticket tons into the measured square yards and see what thickness that implies. If the implied thickness is far from the quote, look at the shape and the hand work before you blame the truck. The coverage figure is a planning check. It is not a specification and it does not name a price.

A practical sequence

Convert square yards to square feet by multiplying by 9.
Divide about 166 square feet per ton by the thickness in inches.
Divide that coverage by 9 to state square yards per ton.
Use the same thickness on the bid and the sketch, then check the plant ticket.

Questions people ask

How many square yards are in the one-inch coverage?

About 18.4 square yards per ton at one inch when you plan compacted hot mix at 145 pounds per cubic foot. That is about 166 square feet divided by 9. At two inches expect about 9.2 square yards, and at three inches about 6.1. These are planning estimates. The plant ticket is the real weight on the load you receive.

Can I price a driveway in square yards and order in tons?

Yes, if both numbers use the same area and the same compacted thickness. Multiply the square yards by 9, then convert those square feet to tons with the 145-pound density. If the thickness changes, the tons change even though the square yards on the bid stay the same.
