About Asphalt Driveway Calculator
Area × thickness gives the compacted volume, and the standard 145 lb/ft³ density (editable) converts it to hot-mix tons. Add a price per ton for a quick material cost.
Common uses
- Estimate tonnage before calling paving contractors
- Price a 2 in overlay versus a full-depth 4 in repave
Example
Input
50 × 12 ft at 3 in, 10% waste, $120/ton
Output
10.88 tons exact → order 11.96 tons ≈ $1,435 material
Limitations
- Thickness is after compaction — loose mix is laid roughly 25% thicker
- Excludes base preparation, tack coat, and paving labor
Frequently asked questions
How many tons of asphalt do I need for my driveway?
Multiply the area by the compacted thickness to get cubic feet, then by 145 lb/ft³, and divide by 2,000. A 600 sq ft driveway at 3 in compacted comes to about 10.9 tons before waste.
How thick should an asphalt driveway be?
2–3 in of compacted hot mix over a solid gravel base is typical for residential driveways; full-depth asphalt or driveways carrying heavy vehicles run 4 in or more. Enter the finished compacted thickness here, not the loose lay.
Why is asphalt laid thicker than the finished thickness?
Rolling compacts hot mix by roughly 25%, so crews lay about 4 in loose to end up with 3 in compacted. This calculator works from the compacted number, which is what tonnage is quoted on.
How much does a ton of asphalt cover?
At 2 in compacted, one ton covers about 83 sq ft; at 3 in it's about 55 sq ft. The figures come straight from the 145 lb/ft³ density — a ton is roughly 13.8 cubic feet of compacted mix, and halving the thickness doubles the coverage.
Is my driveway estimate stored online?
No. The tonnage and cost math runs in your browser only — dimensions and prices are never sent to a server or saved.
