Asphalt Calculator Guide

Understanding Asphalt Measurements

Asphalt is typically measured by weight (tons or tonnes) rather than volume. This calculator converts your project dimensions into the weight of asphalt needed.

Key Factors:

  • ⚖️
    Density

    Asphalt typically weighs about 145 pounds per cubic foot (2,322 kg/m³).

  • 🚜
    Compaction

    Asphalt is compacted during installation, affecting the final volume needed.

  • 📏
    Thickness

    Proper thickness is crucial for durability and load-bearing capacity.

  • 🌡️
    Temperature

    Asphalt must be installed at specific temperatures for proper compaction.

Recommended Asphalt Thickness

Application Recommended Thickness Notes
Residential Driveway 2-3 inches (5-7.5 cm) Suitable for light vehicles
Commercial Driveway 3-4 inches (7.5-10 cm) For heavier traffic
Parking Lot 3-4 inches (7.5-10 cm) Standard commercial use
Heavy-Duty Parking 4-6 inches (10-15 cm) For trucks and heavy equipment
Roadway 4-6 inches (10-15 cm) Depends on traffic volume

Asphalt Pavement Layers

Surface Course (Asphalt) - 1.5-2 inches
Binder Course - 2-3 inches
Base Course (Crushed Stone) - 4-6 inches
Subbase (Gravel) - 4-8 inches
Subgrade (Compacted Soil)

Additional Considerations

  • Base Material:

    A proper base of 4-8 inches of crushed stone or gravel is recommended beneath the asphalt.

  • Waste Factor:

    Consider adding 5-10% extra material to account for waste and spillage.

  • Compaction:

    Asphalt is typically compacted to about 75-85% of its loose volume.

  • Minimum Order:

    Many asphalt suppliers have minimum order requirements (often 5-10 tons).

Frequently Asked Questions

How much does asphalt typically cost?

Asphalt typically costs between $85-$150 per ton, depending on your location, oil prices, and project size. For a more accurate estimate, use our Asphalt Cost Calculator ↗️.

How many square feet does a ton of asphalt cover?

A ton of asphalt typically covers about 80 square feet at a 2-inch thickness, 55 square feet at a 3-inch thickness, or 40 square feet at a 4-inch thickness.

What is the density of asphalt?

Asphalt typically has a density of about 145 pounds per cubic foot (2,322 kg/m³), though this can vary slightly based on the specific mix and aggregate used.

How accurate is this calculator?

This calculator provides a good estimate for planning purposes, but actual asphalt needs may vary based on site conditions, compaction rates, and waste factors. We recommend adding 5-10% extra for waste.

Can I use this calculator for commercial projects?

Yes, this calculator works for both residential and commercial projects. For large commercial projects, we recommend consulting with a professional contractor for the most accurate estimates.
