Does this include compaction loss?

Add 5–10% to the tonnage if you expect extra compaction or waste.

Can I switch to meters?

Convert your measurements to feet before entering them, or build a metric version in a future wave.

Asphalt Volume & Tonnage Calculator

Estimate asphalt tonnage for driveways, parking pads, or road patches by area and thickness.

Results

Area: 1200.00 sq ft
Cubic yards: 11.11
Tons of asphalt: 22.50 tons

How to use this calculator

Enter length and width in feet.
Enter asphalt thickness in inches and mix density (tons per cubic yard).
We calculate area, cubic yards, and tons; add 5–10% for waste/compaction when ordering.

Inputs explained

Length/Width: Project dimensions in feet.
Thickness (in): Paving thickness in inches (commonly 2–4 inches for driveways).
Mix density (tons/yd³): Default 2.025 tons/yd³ (~145 lb/ft³); confirm with your plant.

How it works

Area = length × width. We multiply by thickness (inches ÷ 12) to get cubic feet.

Cubic yards = cubic feet ÷ 27.

Tons = cubic yards × density (default 2.025). Adjust density for different mixes or moisture content.

Formula

Volume (ft³) = L × W × (thickness ÷ 12)
Cubic yards = Volume ÷ 27
Tons = Cubic yards × Density

When to use it

Estimating tonnage for driveways, parking pads, or patches.
Comparing thickness scenarios and their impact on tonnage.
Budgeting deliveries based on truck capacity.

Tips & cautions

Add a buffer for compaction and waste; 5–10% is common.
Use your supplier’s density; different mixes and moisture change tons per yard.
Break irregular areas into rectangles, total the yards/tons, then add your buffer.
Feet/inches inputs only; convert metric first if needed.
Does not include base material—only asphalt.
Density is a user-provided estimate; actual tons can vary with temperature and moisture.

Worked examples

100×12 ft driveway @ 3 in

Area = 1,200 sq ft
Volume ≈ 300 ft³
≈ 11.1 yd³
≈ 22.5 tons

Parking pad 40×30 ft @ 4 in

Tons ≈ 29.6 using 2.025 density

Deep dive

This asphalt calculator converts project dimensions and thickness into square footage, cubic yards, and tons. Enter length, width, thickness, and mix density to size a delivery before you call the plant.

Add 5–10% for compaction/waste and confirm density with your supplier—mix designs and moisture change tons per yard.
