To calculate the total asphalt tonnage, multiply the length (L) by the width (W) and depth (D), then multiply by the specific gravity of asphalt (G). Divide the result by 2000 to convert pounds to tons.
The Asphalt Tonnage Calculator is a tool designed to estimate the amount of asphalt required for paving projects. Whether you’re calculating for a small driveway or a large parking lot, this calculator simplifies the process by converting area measurements into tons.
With the help of this tool, users can determine how much asphalt is needed based on the project’s size in square feet or square meters. From hot mix asphalt to aggregate tonnage, this calculator is essential for contractors and DIY enthusiasts alike, offering accurate estimates for asphalt costs, tonnage, and coverage.

Formula:
Variable | Meaning |
---|---|
T | Total tonnage of asphalt required |
L | Length of the area in feet |
W | Width of the area in feet |
D | Depth or thickness of the asphalt layer (in feet) |
G | Specific gravity of asphalt (typically 2.4) |
2000 | Conversion factor from pounds to tons |
Solved Calculations :
Example 1:
Given Values:
- L = 100 feet
- W = 20 feet
- D = 0.25 feet (3 inches)
- G = 2.4
Calculation | Instructions |
---|---|
T = | Multiply length, width, depth, and specific gravity, then divide by 2000. |
T = | Perform the division. |
T = 0.6 tons | The result gives the total tonnage of asphalt required. |
Answer: T = 0.6 tons
Example 2:
Given Values:
- L = 200 feet
- W = 30 feet
- D = 0.33 feet (4 inches)
- G = 2.4
Calculation | Instructions |
---|---|
T = | Multiply length, width, depth, and specific gravity, then divide by 2000. |
T = | Perform the division. |
T ≈ 2.38 tons | The result gives the total tonnage of asphalt required. |
Answer: T ≈ 2.38 tons
What is Asphalt Tonnage Calculator ?
Calculating asphalt tonnage is crucial for any paving project to ensure that you have the right amount of materials to cover the designated area.
This calculator simplifies this by using the project’s area, whether measured in square feet or square meters, and converting it into tons. This tool helps answer questions such as how much asphalt is needed per square meter and how much a ton of asphalt covers.
With a straightforward formula, the calculator takes into account the density of asphalt and the required depth of the layer to provide an accurate estimate.
Using the Asphalt Tonnage Calculator ensures that you’re not over or under-ordering materials, which can lead to project delays or additional costs.
Whether you’re using it to plan for driveways, parking lots, or roadways, the calculator considers various factors, such as the type of hot mix asphalt used and the aggregate tonnage needed for the base layer.
It’s also a handy tool for contractors to provide accurate pricing and to gauge asphalt costs. With available metric and imperial units, the calculator makes it easy to plan for any size project, ensuring efficiency and cost-effectiveness.
