1. What is Asphalt SY to Tons Conversion?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T = \frac{A_{sy} \times D \times 110}{2000} \]

Where:

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

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

3. Importance of Asphalt Tonnage Calculation

Details: Accurate tonnage calculation ensures proper material ordering, cost estimation, and project planning.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why 110 lbs per square yard per inch?
A: This is the standard weight for hot mix asphalt, though actual weight can vary slightly based on mix design.

Q2: How do I convert square feet to square yards?
A: Divide square feet by 9 to get square yards (1 sq yd = 9 sq ft).

Q3: What's a typical asphalt depth?
A: For driveways, 2-3 inches is common. For roads, 4+ inches is typical.

Q4: Does this include compaction factor?
A: The 110 lb factor already accounts for typical compaction. No additional factor needed.

Q5: How do I calculate for multiple lifts?
A: Calculate each lift separately and sum the tonnage.
