1. What is an Asphalt Milling Calculator?

Definition: This calculator estimates the weight of asphalt millings based on the area in square yards and depth in inches.

Purpose: It helps construction professionals and contractors determine how much milled asphalt will be produced during pavement removal.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight of asphalt millings (tons)
• \( A_{sy} \) — Area (square yards)
• \( D \) — Depth (inches)
• 140 — Density of asphalt (lb/ft³)
• 2000 — Pounds per ton

Explanation: The area is multiplied by depth and density, then converted from pounds to tons.

3. Importance of Asphalt Milling Calculation

Details: Accurate calculations help with project planning, disposal costs, and recycling efforts for milled asphalt.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why use 140 lb/ft³ density?
A: This is the standard density for compacted asphalt, though actual density may vary slightly.

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

Q3: Does this account for compaction?
A: The calculation uses compacted asphalt density. For loose millings, you may need to adjust.

Q4: What's the typical milling depth?
A: Common milling depths range from 2-4 inches for surface removal.

Q5: Can I use this for new asphalt calculations?
A: Yes, the same formula works for estimating new asphalt tonnage.
