Asphalt Calculator — Tons, Thickness & Cost

Convert driveway or paving dimensions and compacted thickness into cubic yards, asphalt tons, ordering allowance, and cost.

Calculated and reviewed by HomeTaskKit Editorial Team ·
Quick answer

Asphalt tonnage is paved area × compacted thickness × compacted mix density, divided by 2,000 pounds per U.S. ton. The selected allowance then creates a supplier-ready planning quantity.

Your planning estimate19.03 tons of asphalt

1,000 sq ft · 9.26 yd³ compacted volume · 145 lb/ft³ planning density.

Measured need18.13 tons before allowanceBuy / plan19.03 tons after 5% allowance
Formula: area × compacted thickness × mix density ÷ 2,000 × allowance

Asphalt density varies with the approved mix, aggregate, binder, temperature, compaction target, and plant ticket. Use the producer or project-specific density when available.

Enter the required compacted thickness. Loose lift thickness, number of lifts, base preparation, drainage, edge support, access, trucking, minimum loads, and local specifications require contractor or engineer confirmation.

Use it well

Step by step

  1. 1

    Measure each paving section and enter the specified compacted thickness, not an assumed loose depth.

  2. 2

    Replace the planning density with the mix producer's or project specification's compacted density when available.

  3. 3

    Confirm base, drainage, lifts, compaction, access, trucking, plant minimums, temperature, joints, edge support, and local specifications with the paving professional.

Worked example

Check the estimate before you buy

Convert paving area and compacted asphalt thickness into cubic yards, tons, ordering allowance, and an optional material cost.

Example

A 50 × 20 ft paved area at 3 in compacted thickness contains 250 cubic feet. At a 145 lb/ft³ planning density, that is about 18.13 tons before allowance and 19.03 tons after 5%.

How the calculation works

Area × compacted thickness gives volume. Volume × compacted mix density ÷ 2,000 gives U.S. tons, and the selected allowance is applied to the tonnage.

Planning checklist

Before you place the order

  • Use the approved mix producer's density rather than a generic value whenever possible.
  • Enter compacted—not loose—thickness and calculate separate lifts when specifications differ.
  • Confirm base, drainage, joints, compaction, weather, plant minimums, trucking, access, and placement sequence with the paving contractor.
Common questions

Asphalt Calculator — Tons, Thickness & Cost FAQ

How much does a cubic yard of asphalt weigh?

It varies by mix and compaction. At 145 lb/ft³, one cubic yard weighs about 3,915 lb or 1.96 U.S. tons, but project-specific density should replace that planning value.

Should asphalt thickness be entered loose or compacted?

Enter the required compacted thickness. Loose placement thickness and compaction procedures are determined by the mix, equipment, lift, and specification.

Does the result include the aggregate base?

No. Use the gravel calculator for each base layer and keep its depth, density, and compaction separate.

Can I order exactly the displayed tons?

Supplier increments, plant minimums, truck payloads, site loss, and field yield affect the practical order. Confirm tonnage and tickets with the producer and paving contractor.
