1. What is the MN Asphalt Calculator Tons?

Definition: This calculator estimates the weight of asphalt needed based on Minnesota's standard calculation method.

Purpose: It helps contractors and engineers determine how much asphalt is required for paving projects in Minnesota.

2. How Does the Calculator Work?

The calculator uses the Minnesota standard 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 — Minnesota standard weight (lbs per square yard per inch)
2000 — Conversion from pounds to tons

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

3. Importance of Accurate Asphalt Calculation

Details: Proper asphalt estimation ensures project budgeting, material ordering, and pavement performance.

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 does Minnesota use 110 lbs/sy-in?
A: This is the standard weight factor established by the Minnesota Department of Transportation for asphalt calculations.

Q2: Can I use this calculator for other states?
A: While the calculation method is similar, other states may use different standard weights (e.g., 112 lbs/sy-in).

Q3: How do I convert square feet to square yards?
A: Divide square footage by 9 (1 sq yd = 9 sq ft).

Q4: Does this include compaction factor?
A: Yes, the 110 lbs/sy-in factor already accounts for typical compaction.

Q5: How much extra should I order?
A: Typically 5-10% extra is recommended for waste, overlaps, and irregularities.
