1. What is a SY Asphalt to Ton Calculator?

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 projects.

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 of asphalt (square yards)
\( D \) — Depth of asphalt (inches)
110 — Standard weight of asphalt per square yard per inch (lbs)
2000 — Conversion factor (lbs to tons)

Explanation: The formula calculates the total weight in pounds then converts it to tons.

3. Importance of Asphalt Tonnage Calculation

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

4. Using the Calculator

Tips: Enter the asphalt area in square yards and depth in inches. Both 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. Actual weight may vary slightly based on mix design.

Q2: How do I convert square feet to square yards?
A: Divide square footage by 9 (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 lbs/yd²/in already accounts for typical compaction.

Q5: How do I account for waste?
A: Add 5-10% to the calculated tonnage for project contingencies.
