Asphalt, gravel and dirt calculator
Type length, width and depth. Get tons and truckloads as you type.
Depth is the compacted thickness. Ask the plant for the mix's actual density.
The asphalt formula
tons = length (ft) × width (ft) × depth (in) ÷ 12 × 145 lb/ft³ ÷ 2,000
Worked example for a parking lot, driveway or road patch: 528 ft × 30 ft at 4 in is 205.3 cubic yards and 401.9 tons with 5% extra, or 27 loads.
Plants sell hot mix by the ton, so the answer is in tons. Depth is the compacted thickness: a 2 in surface course, a 3 to 4 in base on a lot, more on a road.
Asphalt by the square foot
| Depth | 100 sq ft (10 × 10) | 1,000 sq ft |
|---|---|---|
| 2 in | 1.21 t | 12.1 t |
| 3 in | 1.81 t | 18.1 t |
| 4 in | 2.42 t | 24.2 t |
| 6 in | 3.63 t | 36.3 t |
No waste added in the table. Weight used: 3,915 lb per cubic yard. Compacted hot mix asphalt runs about 145 lb/ft³ (about 110 lb per square yard per inch), the figure state DOTs and the Asphalt Institute use for estimating; spec MAT3.js.
Save it to a job. Dozer checks it against what's laid.
Saved estimates go on the site. Dozer adds up the haul tickets and the paver's tons each night and tells you if you're running over.
- Estimate vs. tons laid, every night
- Haul tickets read from a photo
- Overrun flagged before the next order
- Every estimate kept with the job

Questions crews ask
How do I calculate asphalt tons?
Multiply length by width in feet, then by depth in inches divided by 12. That's cubic feet. Multiply by 145 lb per cubic foot and divide by 2,000 for tons. Add 5% for waste.
How much does a cubic yard of asphalt weigh?
About 3,915 lb, or 1.96 tons. Depth is the compacted thickness. Ask the plant for the mix's actual density.
How many tons for 528 by 30 ft at 4 in?
About 401.9 tons with 5% extra, or 27 truckloads at 15 tons a load.
How much asphalt fits in a dump truck?
This calculator uses 15 tons a load. A tandem dump usually hauls 10 to 15 tons, a tri-axle 15 to 20 and a semi end-dump about 22 to 25; the legal weight on your roads decides.
