1. What is Asphalt Ton to SY Conversion?

Definition: This calculator converts the weight of asphalt in tons to square yards (SY) coverage based on the specified depth.

Purpose: It helps paving professionals and contractors determine how much area a given weight of asphalt will cover at a particular thickness.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( A_{sy} \) — Area in square yards
• \( T \) — Weight of asphalt (tons)
• \( D \) — Depth of asphalt (inches)

Explanation: The formula converts tons to pounds (×2000), then divides by the product of depth (inches) and 110 (lbs per square yard per inch of asphalt).

3. Importance of Asphalt Conversion

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

4. Using the Calculator

Tips: Enter the asphalt weight in tons and desired depth in inches (default 2"). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 110 in the formula?
A: This represents the approximate weight (in pounds) of 1 square yard of asphalt at 1 inch thick.

Q2: What's a typical asphalt depth?
A: For driveways, 2-3 inches is common. For roads, 3-5 inches is typical depending on traffic load.

Q3: How does temperature affect calculations?
A: Hot-mix asphalt density can vary slightly with temperature, but the 110 lb/SY/inch is a good average.

Q4: Can I use this for cold-mix asphalt?
A: No, cold-mix has different density. Use 105 lb/SY/inch instead of 110 for cold-mix.

Q5: How do I calculate tons from square yards?
A: Rearrange the formula: \( T = \frac{A_{sy} \times D \times 110}{2000} \)
