1. What is an Asphalt Square Yards to Ton Calculator?

Definition: This calculator converts an area of asphalt in square yards to weight in tons based on the depth of the asphalt layer.

Purpose: It helps paving professionals and contractors estimate the amount of asphalt needed for projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight of asphalt (tons)
• \( A_{sy} \) — Area (square yards)
• \( D \) — Depth (inches)
• 110 — Standard asphalt weight (lbs per square yard per inch)
• 2000 — Conversion from pounds to tons

Explanation: The area is multiplied by depth and standard weight, then converted from pounds to tons.

3. Importance of Asphalt Tonnage Calculation

Details: Accurate tonnage estimates ensure proper material ordering, cost control, and efficient project planning.

4. Using the Calculator

Tips: Enter the area in square yards and depth in inches. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is 110 lbs used in the formula?
A: This is the standard weight for hot mix asphalt per square yard per inch of thickness.

Q2: Does this work for different asphalt mixes?
A: The 110 lb factor is for standard hot mix. Some mixes may vary slightly (105-115 lbs).

Q3: How do I measure the area?
A: Multiply length × width in yards, or convert from square feet (divide by 9).

Q4: What depth should I use?
A: Use your planned asphalt thickness. Common depths are 2-4 inches for driveways.

Q5: Does this include compaction factor?
A: The 110 lb factor already accounts for typical compaction. No additional factor needed.
