Asphalt calculator — tons of hot mix for a driveway or lot

Enter the paved length and width in feet and the compacted thickness in inches. Density varies by mix; use your plant's figure when you have it.

TaskBider drafters, detailers and BIM coordinators work remotely and every listing shows the pay. Typical published range for this work: $18–$45/hr.

tons = L(ft) × W(ft) × thickness(in) ÷ 12 × density(lb/ft³) ÷ 2,000

145 lb/ft³ is a common planning density for compacted hot-mix asphalt. Base course, edges and waste are not included.

Input	Result
50 × 12 ft driveway, 3 in	150 ft³ × 145 ÷ 2000 = 10.88 tons
100 × 60 ft lot, 2 in	1,000 ft³ → 72.5 tons

Multiply area in ft² by thickness in feet, then by density (about 145 lb/ft³), and divide by 2,000.

Residential driveways are often specified around 2–3 in of surface course over a prepared base, but follow your engineer or local spec.
