How it’s calculated
Hot mix is bought by weight, so the estimate converts area × compacted thickness to a volume, then to US tons using the mix density.
Example (default example rates): 1,000 ft² at 3 in: 1,000 × 0.25 × 145 = 36,250 lb; +5% = 38,062.5 lb = 19.03 tons. Asphalt 19.03 × $120 = $2,283.75; labor 1,000 ft² × $1.75 = $1,750; mobilization $500. Direct cost $4,533.75; +20% = $5,440.50; 7% tax on asphalt = $159.86. TOTAL ≈ $5,600.36 (≈ $5.60/ft²).
Check: the Asphalt Institute’s rule of thumb of 110 lb per yd² per inch gives 111.1 yd² × 3 in × 110 = 36,667 lb (18.3 tons), within about 1% of the density method.
This is a planning estimate only. It does not include anything not entered above, such as permits, inspections, engineering, site preparation, demolition or disposal (unless entered), access or equipment problems, regional surcharges, contingency or price changes. Get written quotes before committing. For paving that includes removal of old pavement, excavation, aggregate base, drainage, tack coat, striping and sealcoating.
Frequently asked questions
How many tons of asphalt per square foot?
At 145 lb/ft³, each inch of compacted thickness weighs about 12.1 lb per ft², so 1,000 ft² at 1 in is about 6 tons, and at 3 in about 18 tons (before waste).
Why charge a mobilization fee?
Hauling a paver, roller and crew to a small job costs nearly as much as to a large one. A flat mobilization fee keeps small jobs profitable.
Should I price labor per ton or per square foot?
Large jobs are often priced per ton placed; driveways are often priced per square foot. Pick whichever matches how you track your crew’s productivity.
What thickness does a driveway need?
Residential driveways are commonly 2–3 in of hot mix over a compacted aggregate base. Heavier traffic and poor soils need more; follow local practice or an engineer’s design.
