Frequently Asked Questions
How do I calculate how much asphalt I need?
To calculate asphalt needed: 1) Measure the area length and width in feet, 2) Multiply to get square footage, 3) Multiply by desired thickness in feet, 4) Multiply by 145 lbs (asphalt density per cubic foot), 5) Divide by 2000 to get tons. Our calculator does this automatically for any shape.
How many tons of asphalt do I need for a driveway?
A typical 2-car driveway (about 600 sq ft) with 2-3 inches of asphalt requires approximately 7-10 tons. For exact calculations, use our asphalt calculator with your specific dimensions and desired thickness.
What is the standard density of asphalt?
Standard hot mix asphalt density is approximately 145 lbs per cubic foot or 2.3 tons per cubic yard. This can vary slightly based on the specific mix design and aggregate used.
How thick should asphalt be for a driveway?
Residential driveways typically require 2-3 inches of asphalt over a 4-8 inch base. Commercial parking lots need 3-4 inches, while roads may require 4-6 inches depending on traffic load.
What shapes can I calculate with this tool?
Our asphalt calculator supports four common shapes: rectangles (standard driveways), circles (roundabouts or curved areas), triangles (triangular lots), and trapezoids (irregular shaped areas).
How do I convert asphalt thickness from inches to feet?
To convert inches to feet, divide by 12. For example, 3 inches of asphalt = 0.25 feet (3 ÷ 12 = 0.25). Our calculator automatically handles this conversion when you select inches as your unit.
What's the difference between US tons and metric tonnes?
US tons (short tons) = 2,000 lbs. Metric tonnes = 2,204.62 lbs (1,000 kg). Our calculator shows both measurements so you can order from suppliers using either system.
Can I use this for commercial paving projects?
Yes, this calculator works for both residential and commercial projects including parking lots, roads, pathways, and industrial paving. Simply enter your dimensions and desired thickness.
