Asphalt Calculator – Estimate Asphalt Quantity and Cost Easily
What asphalt is made of?
This Asphalt Calculator helps you accurately estimate how much asphalt material you need for your driveway, parking lot, or road project. Simply enter the length, width, and depth of the area, and the calculator will compute the total volume in cubic feet, cubic yards, and tons of hot mix asphalt (HMA).
How to Use the Asphalt Calculator
Input the dimensions of the area you want to pave:
- Length (in feet)
- Width (in feet)
- Depth (in inches)
The tool will calculate the total volume and convert it to asphalt tonnage based on standard asphalt density.
Asphalt Volume & Tonnage Formula
- Volume (ft³): Length × Width × (Depth ÷ 12)
- Volume (yd³): Volume (ft³) ÷ 27
- Tons: Volume (ft³) × Asphalt Density ÷ 2000
Note: Average asphalt density = 145 lbs/ft³ (can vary based on mix type and compaction).
Common Use Cases
- Residential driveway paving
- Road or street resurfacing
- Parking lot construction
- Sports courts, walkways, and more
Why Use an Asphalt Calculator?
Estimating asphalt manually can be confusing and lead to under- or over-ordering. Our asphalt calculator ensures precision by factoring in the area and desired depth, converting the result into cubic yards and tons for ordering hot mix asphalt (HMA). Whether you're a contractor or homeowner, this tool saves time and money during planning.
Frequently Asked Questions (FAQs)
How much does 1 ton of asphalt cover?
One ton of asphalt typically covers around 80 sq ft at 2 inches depth, or 40 sq ft at 4 inches depth.
How thick should asphalt be?
Standard residential driveways use 2–3 inches of asphalt. Roads or commercial projects may require 4–6 inches or more.
What is the density of asphalt?
Hot mix asphalt has a density of approximately 145 lbs per cubic foot or 2,320 kg/m³.
Can I use this calculator for concrete?
This calculator is specific to asphalt. For concrete, use a concrete calculator instead.
Does this tool factor in compaction?
No, it calculates raw material volume. Add 5–10% extra to account for compaction and material loss.
