1. What is a Weight of Asphalt per Square Yard Calculator?

Definition: This calculator estimates the weight of asphalt in pounds per square yard based on thickness and density.

Purpose: It helps construction professionals and paving contractors determine asphalt weight for proper structural support and material estimation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W_{sy} \) — Weight per square yard (pounds/yd²)
• \( D \) — Asphalt thickness (inches)
• \( \rho \) — Asphalt density (pounds/cubic foot)

Explanation: The formula converts thickness from inches to feet, calculates volume per square yard, then multiplies by density to get weight.

3. Importance of Asphalt Weight Calculation

Details: Proper weight estimation ensures structural integrity, proper base preparation, and accurate material ordering for paving projects.

4. Using the Calculator

Tips: Enter the asphalt thickness in inches and density in lb/ft³ (default 145 lb/ft³ for typical hot mix asphalt). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical asphalt density?
A: Most hot mix asphalt has a density of 145 lb/ft³, but this can range from 140-150 lb/ft³ depending on mix design.

Q2: How does thickness affect weight?
A: Weight increases linearly with thickness - double the thickness means double the weight per square yard.

Q3: Why calculate weight per square yard?
A: Paving projects are often measured in square yards, making this a convenient unit for material estimation.

Q4: How do I convert this to total project weight?
A: Multiply the result by your total area in square yards to get total asphalt weight needed.

Q5: Does this include compaction factor?
A: The density value should reflect the compacted asphalt density. For loose mix, use a lower density value.
