Asphalt Driveway Calculator
Calculate asphalt tonnage for a new driveway or resurfacing project. Get exact quantities and cost estimates for hot-mix asphalt (HMA) based on driveway size, thickness, and local asphalt prices.
Formula & Reference

|---|---|---|
| Asphalt Driveway Calculator | Tons = Length x Width x Thickness x 0.062 (for 2-inch depth, 145 lb/cu ft asphalt) | tons of asphalt |
Step-by-Step Examples
50x12 ft, 2-inch each layer (new build), $100/ton.
- Area = 600 sq ft
- Surface tons = 600x(2/12)x145/2000 = 7.25 tons per layer
- New build: 7.25x2 = 14.5 tons total
- Cost = 14.5 x $100 = $1,450 material only
80x20 ft, resurface 2 in.
- Area = 1,600 sq ft
- Tons = 1,600x(2/12)x145/2000 = 19.3 tons
- Cost at $100/ton = $1,933 materials only
Long 100x12 ft + 30x30 ft turnaround, 2 in resurface.
- Area = 1,200 + 900 = 2,100 sq ft
- Tons = 2,100x(2/12)x145/2000 = 25.4 tons
Real-World Applications
Common Mistakes to Avoid
A new asphalt driveway requires a gravel base (4-8 inches) PLUS 2-3 inches of asphalt. The gravel base can be as expensive as the asphalt. Total installed costs account for both.
Residential driveways: minimum 2 inches of compacted asphalt for light use, 3 inches for regular car traffic. Less than 2 inches will crack and pothole quickly.
Asphalt paving prices vary significantly by region, season, and contractor. Always get 3+ bids for any paving project.
