5.80 tons
480 ft² at 2 in thickness.
- Volume80.0 ft³
- Weight11,600 lb
- Tons5.800
- Density145 lb/ft³
Step-by-step
- Volume = 40 × 12 × 0.167 = 80.00 ft³.
- Weight = 80.00 × 145 = 11,600 lb.
- Tons = 11,600 ÷ 2000 = 5.800 tons.
How to use this calculator
- Enter the paved area and thickness.
- Use density 145 lb/ft³ for standard hot-mix; adjust if your supplier specifies a different density.
- Check the breakdown for total weight if your supplier prices in tons or short tons.
About this calculator
Asphalt is sold by the ton, and 1 cubic foot of compacted hot-mix weighs about 145 lb. A residential driveway typically uses 2-3 inches of asphalt over a properly prepared 4-6 inch gravel base. Always order at least 5% extra to cover edge spread and roller compaction.
Frequently asked
2 inches for an overlay on existing pavement. 3 inches for a new driveway over a gravel base. 4+ inches for parking lots and high-traffic surfaces.
