1. What is the Tons of Asphalt per Square Yard Calculator?

Definition: This calculator estimates the weight of asphalt in tons per square yard based on the depth of the asphalt layer.

Purpose: It helps construction professionals and paving contractors determine asphalt quantities needed for paving projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T_{sy} \) — Tons of asphalt per square yard
• \( D \) — Depth of asphalt (inches)
• 110 — Pounds per square yard per inch (standard asphalt density)
• 2000 — Pounds per ton (conversion factor)

Explanation: The formula converts depth in inches to weight in tons per square yard using standard asphalt density values.

3. Importance of Asphalt Weight Calculation

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

4. Using the Calculator

Tips: Simply enter the planned asphalt depth in inches. The calculator will show the weight in tons per square yard.

5. Frequently Asked Questions (FAQ)

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

Q2: Does this work for different asphalt mixes?
A: The 110 value is for standard HMA. For other mixes (like porous asphalt), adjust the density accordingly.

Q3: How do I calculate total tons needed for a project?
A: Multiply the result by your total area in square yards. For example: 0.055 tons/yd² × 1000 yd² = 55 tons.

Q4: What's a typical asphalt depth for driveways?
A: Residential driveways typically use 2-3 inches, while commercial pavements may use 4+ inches.

Q5: Does this include compaction factor?
A: The 110 lbs factor already accounts for compacted asphalt density. No additional compaction factor is needed.
