Asphalt Calculator (2026) - Tonnage, Cost & Coverage Estimator

At standard 2-inch thickness, hot mix asphalt covers about 80-85 square feet per ton. At 3 inches, one ton covers 55-60 square feet. At 4 inches, one ton covers roughly 40-45 square feet.

The quick formula: multiply square footage by thickness in inches, divide by 12, multiply by 145 (density), then divide by 2,000 to get tons. Always add 8-10% for waste.

Hot mix asphalt costs $80-$150 per ton in 2026 depending on your region. Southeast states average $80-$110/ton, Midwest $90-$120/ton, and Northeast $110-$150/ton. Recycled asphalt (RAP) costs $40-$80/ton.

Installed costs including labor run $3-$9 per square foot for most residential projects. A typical 1,000 sq ft driveway costs $2,000-$6,000 fully installed. See our asphalt cost calculator for a detailed breakdown.

Standard residential driveways use 2-3 inches of compacted hot mix asphalt over a 4-6 inch compacted gravel base. For driveways that will support RVs, boats, or heavy trucks, use 3-4 inches of asphalt and 6-8 inches of base.

The gravel base is just as important as the asphalt thickness. A well-prepared, compacted base prevents cracking, settling, and ruts far better than adding extra asphalt on a weak foundation.

Hot mix asphalt (HMA) is fresh asphalt produced at 300-350°F, offering the best durability, weather resistance, and appearance. It is the standard choice for driveways, parking lots, and roads.

Recycled asphalt (RAP - Reclaimed Asphalt Pavement) is ground-up old asphalt that costs 40-60% less. It works well for rural driveways and low-traffic areas but does not compact or seal as cleanly as hot mix. It also tends to soften in extreme heat and may track onto shoes and vehicles.

For a gravel base, multiply your project area (sq ft) by the base depth in feet, then multiply by 1.35 (compaction factor for gravel) to get cubic feet. Divide by 27 for cubic yards, then multiply by roughly 1.5 tons/yd³ for the weight.

For a 1,000 sq ft driveway with a 4-inch base: 1,000 × 0.333 ft × 1.35 = 450 cubic feet = 16.7 cubic yards = about 25 tons of gravel. Use our gravel calculator for a more precise estimate.

Asphalt is typically 30-50% cheaper to install than concrete. In 2026, asphalt driveways cost $3-$9/sq ft installed vs $6-$14/sq ft for concrete. However, concrete lasts 30-50 years vs 20-30 years for asphalt and requires less maintenance.

Asphalt needs sealing every 3-5 years and re-paving every 20-30 years. Concrete is more durable but cracks are harder and more expensive to repair. Read our full concrete vs asphalt comparison to decide which is right for your project.

Asphalt should be laid when air temperatures are above 50°F and rising. The ideal paving season is April through October in most US states. In southern states like Florida, Texas, and Arizona, paving can happen year-round.

Avoid paving when rain is forecast within 24 hours or when ground temperatures are below 40°F. Cold temperatures cause asphalt to cool and harden too quickly for proper compaction, leading to a weak surface that cracks prematurely.

For irregular shapes, break the area into rectangles, triangles, and circles, calculate each section separately, and add the totals. Our calculator supports rectangles, circles, triangles, and trapezoids to cover most project shapes.

For very complex shapes, use the rectangle method by measuring the overall bounding box and adding 10-15% waste to account for cutouts and irregular edges. Alternatively, measure the area using a measuring wheel for the most accurate takeoff.
