Planning to pave a driveway, parking lot, or repair damaged asphalt? Our free asphalt calculator helps you determine exactly how many tons of asphalt you need. Get accurate estimates for hot mix, cold mix, warm mix, porous, or recycled asphalt with instant cost projections and waste factors built in.
Asphalt is sold by the ton but measured by volume. The key to accurate estimation is understanding density—hot mix asphalt weighs approximately 145 pounds per cubic foot. For residential driveways, 2-3 inches of asphalt over a proper base is standard, while commercial applications typically require 3-4 inches or more.
Asphalt Tonnage Formula
Tons = (Length × Width × Thickness × Density) ÷ (2000 × 12)Order the right amount—too little means costly delays, too much wastes money.
Know your material costs upfront before getting contractor quotes.
Different asphalt types have different densities—this affects total tons needed.
Built-in waste factors ensure you don't run short during installation.
Understand material quantities whether doing it yourself or hiring a contractor.
Standard 2-3 inch thickness over compacted gravel base. Hot mix asphalt is most common for durability.
Commercial applications typically need 3-4 inches for heavier vehicle traffic and longer life.
Cold mix asphalt works best for DIY repairs—it's workable at ambient temperatures.
Porous asphalt allows water drainage, reducing runoff and helping with stormwater management.
At 2 inches thick, one ton of hot mix asphalt covers approximately 80-100 square feet. At 3 inches, coverage drops to about 55-65 square feet per ton. Coverage varies slightly by asphalt type and compaction.
