The Asphalt Cost Per Square Foot Formula

The cost per square foot is a key metric for comparing pricing across different projects and contractors. The formula is derived by first calculating the total area of the paved surface and then dividing the total cost of the asphalt by that area.

Asphalt Cost Per Square Foot Formula:

ACSF=T/12V​AC​

Where:

• ACSF = Asphalt Cost Per Square Foot ($/ft²)
• AC = Total Cost of the Asphalt ($)
• V = Volume of Asphalt (ft³)
• T = Thickness of the asphalt (in)

The denominator, V/(T/12), is used to calculate the total area of the paved surface. This is derived from the standard volume formula (V=L×W×H) where area is represented by L×W. By rearranging the volume formula to solve for area, we get Area=V/H. The thickness (T) is divided by 12 to convert it from inches to feet, ensuring all units are consistent.

Example Problem:

Let’s calculate the cost per square foot for a project with the following specifications:

1. Total Cost of Asphalt: $4,500
2. Volume of Asphalt: 1,200 ft³
3. Thickness: 4 inches
4. Apply the Formula: ACSF=4/121200​4500​ ACSF=1200/0.3334500​ ACSF=3603.64500​ ACSF=1.25

In this example, the asphalt cost per square foot is $1.25.

FAQs

What is the average asphalt cost per square foot?

The average cost per square foot for basic asphalt work is approximately $3.70, but this can fluctuate widely. This figure typically includes not just the cost of the raw asphalt but also labor, equipment, and other associated costs. The final price you pay can be as low as $2.00 per square foot for large, simple projects or as high as $6.00 per square foot for smaller, more complex jobs.

How does asphalt compare to other paving materials like concrete?

Asphalt is a popular choice for driveways and parking lots due to its versatility, durability, and affordability. Compared to concrete, asphalt is typically more budget-friendly on an initial installation basis. While concrete is more durable and has a longer lifespan, asphalt is easier and cheaper to repair and is more flexible, making it less prone to cracking in freeze-thaw cycles.

Can a larger project have a lower cost per square foot?

Yes, this is a common principle of economies of scale. When a paving crew is mobilized for a large project, the fixed costs—like bringing a paver, rollers, and dump trucks to the site—are spread out over a greater number of square feet, which reduces the per-square-foot price.

What is the difference between the cost of materials and the total project cost?

The cost of materials refers to the price of the raw asphalt mix itself, often quoted per ton. The total project cost includes all other expenses, such as the cost of the sub-base materials (like gravel), labor for site preparation and paving, equipment rental, and profit for the contractor. An Asphalt Cost Per Square Foot Calculator primarily helps you analyze the material cost component of your budget.
