A 1,000-square-foot driveway at 3 inches compacted depth contains 250 cubic feet before applying density.
Estimate asphalt volume and tons from area, compacted depth and material density. The result is intended for quick estimates, checking arithmetic and comparing scenarios. When a result affects a contract, tax filing, medical decision, building-code requirement or other high-stakes situation, verify the result with the appropriate professional or authoritative source.
For 1,000 square feet at 3 inches deep, the volume is 250 cubic feet. At 145 pounds per cubic foot with 5% allowance, that is about 19 tons.
Increase the allowance for uneven subgrades or compaction planning rather than ordering exactly the theoretical volume.
Density, lift thickness, and delivered tonnage vary by mix; confirm quantities with the paving contractor.

Estimate asphalt volume and tons from area, compacted depth and material density.
Cubic feet = area × depth in feet. Tons = cubic feet × density in pounds per cubic foot ÷ 2,000.
