1. What is a Square Feet to Tons of Asphalt Calculator?

Definition: This calculator converts area measurements in square feet to weight in tons for asphalt paving projects.

Purpose: It helps contractors and project planners estimate the amount of asphalt needed based on project area and desired thickness.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight of asphalt (tons)
• \( A \) — Area (square feet)
• \( D \) — Depth (feet)
• \( \rho \) — Density of asphalt (pounds per cubic foot, typically 145)

Explanation: The formula calculates volume in cubic feet, converts to weight in pounds using density, then converts to tons by dividing by 2000.

3. Importance of Asphalt Weight Calculation

Details: Accurate weight estimation ensures proper material ordering, cost control, and project planning for paving projects.

4. Using the Calculator

Tips: Enter the area in square feet, depth in feet, and density (default 145 lb/ft³). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the density typically 145 lb/ft³?
A: This is the standard density for hot mix asphalt, though it can vary slightly based on mix design and temperature.

Q2: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 3 inches = 0.25 feet).

Q3: Does this include compaction factor?
A: No, for compacted asphalt, you may need to increase the calculated amount by 5-10%.

Q4: How accurate is this calculation?
A: It provides a good estimate, but actual needs may vary based on site conditions and compaction.

Q5: What's the 2000 divisor for?
A: It converts pounds to tons (1 ton = 2000 pounds).
