1. What is a Cold Patch Asphalt Calculator?

Definition: This calculator estimates the weight of cold patch asphalt needed based on the area dimensions and depth.

Purpose: It helps construction professionals and DIYers determine how much cold patch asphalt is required for repair projects.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight of cold patch asphalt (tons)
• \( L \) — Length of area (feet)
• \( W \) — Width of area (feet)
• \( D \) — Depth of area (feet)
• 140 — Density of cold patch asphalt (lb/ft³)
• 2000 — Conversion from pounds to tons

Explanation: The volume is calculated (L×W×D) then multiplied by density and converted to tons.

3. Importance of Cold Patch Asphalt Calculation

Details: Proper calculation ensures you purchase the right amount of material for pothole repairs and other asphalt maintenance.

4. Using the Calculator

Tips: Enter the length, width, and depth in feet. All values must be > 0. Depth is typically 2-4 inches (convert to feet: 2" = 0.1667 ft).

5. Frequently Asked Questions (FAQ)

Q1: Why use 140 lb/ft³ density?
A: Cold patch asphalt has lower density than hot mix (typically 140-145 lb/ft³) due to different composition.

Q2: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 3 inches = 3/12 = 0.25 feet).

Q3: Does this include compaction factor?
A: No, cold patch requires compaction but the density already accounts for this in the calculation.

Q4: How much area does a ton cover?
A: At 2" depth, 1 ton covers about 85-90 sq ft (varies slightly by compaction).

Q5: Should I order extra material?
A: Yes, consider adding 5-10% to account for irregularities and compaction.
