How Many Tons of Asphalt for a 24 by 36 Driveway?

Twenty-four by thirty-six covers 864 square feet, more than a small apron and less than a lot. Plan about 10.4 tons at two inches and about 15.7 tons at three inches. A one-inch change is about 5.2 tons. The plant ticket is the real weight.

The inch is now a truck slice

The inch starts to matter on 864 square feet, which is 24 by 36. At two inches, 864 times 2 times 145 divided by 24,000 equals 250,560 divided by 24,000, which is 10.44, about 10.4 tons. At three inches, 864 times 3 times 145 divided by 24,000 equals 375,840 divided by 24,000, which is 15.66, about 15.7 tons. One inch of thickness is 864 times 145 divided by 24,000, which is 5.22 tons. That single inch is larger than the entire three-inch order for a 12 by 24 driveway. Getting the depth wrong is no longer a small miss. These are planning estimates at 145 pounds per cubic foot of compacted hot mix. The plant ticket is the real weight. Record the inches beside 10.4 or 15.7 every time you repeat them.

How it compares with the shorter wide drive

A 24 by 30 is 720 square feet, about 13.1 tons at three inches. Six more feet of length at a 24-foot width is 144 square feet. At three inches, 144 times 3 times 145 divided by 24,000 equals 2.61, about 2.6 tons. About 13.1 plus about 2.6 is about 15.7. If the household measured to the sidewalk in one sketch and to the garage in another, that six-foot argument is tons, not taste. A flare wider than 24 feet is additional. Average the flare and add it. Do not inflate the whole 36-foot length to the street width. Only the flared distance gets the wider average.

Yield, base, and the ticket

An area this open can track the paver formula more closely than a narrow lane, and the edges still add some thickness where they are raked. Five percent of 15.7 is about 0.8 ton. Use that only for minor variation. A wrong width of two feet along 36 feet is 72 square feet, about 1.3 tons at three inches, which already exceeds the allowance. Measure twice. Gravel under the mat stays on its own line, near 1.4 tons per cubic yard, with the quarry ticket as the real stone weight. Two inches and three inches are planning depths, not code sentences. When the trucks leave, add the scale tickets and set them next to the 864 square feet you built.

A practical sequence

Multiply 24 by 36 to get 864 square feet.
Plan about 10.4 tons at two inches or about 15.7 tons at three inches.
Treat one inch of depth as about 5.2 tons so a thickness error stays visible.
Call the result a planning estimate and confirm the weight on the plant ticket.

The mistake to skip

Changing the thickness by an inch and expecting the tonnage to move only a little.

Questions people ask

How many tons is 24 by 36 at two inches?

About 10.4 tons. The area is 864 square feet, and 864 times 2 times 145 divided by 24,000 equals 10.44. About 15.7 tons is the three-inch figure. Both are planning estimates at 145 pounds per cubic foot. The plant ticket is the real weight.

How many tons is one extra inch on this drive?

About 5.2 tons. Multiply 864 by 145 and divide by 24,000, which is 5.22. That is why 10.4 and 15.7 differ by about that amount. Confirm the compacted thickness before you order, because an inch here is a large load.
