1. What is Tarmac Tonnage Calculation?

Tarmac tonnage calculation estimates the weight of tarmac material needed for a specific area, similar to asphalt calculations. It helps in project planning, material ordering, and cost estimation for construction projects.

2. How Does the Calculator Work?

The calculator uses the tarmac tonnage formula:

Where:

• \( \text{Length} \) — Length in feet (ft)
• \( \text{Width} \) — Width in feet (ft)
• \( \text{Thickness} \) — Thickness in inches (in)
• \( \text{Density} \) — Density in pounds per cubic foot (lb/cu ft, typically 145)

Explanation: The formula converts all measurements to consistent units and calculates the weight in tons, accounting for the material density.

3. Importance of Tarmac Tonnage Calculation

Details: Accurate tonnage calculation is crucial for construction projects to ensure proper material ordering, minimize waste, control costs, and meet project specifications.

4. Using the Calculator

Tips: Enter length and width in feet, thickness in inches, and density in lb/cu ft (default is 145). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density for tarmac?
A: The typical density for tarmac is approximately 145 lb/cu ft, similar to asphalt.

Q2: Why divide by 12 in the formula?
A: Dividing by 12 converts thickness from inches to feet to maintain consistent units throughout the calculation.

Q3: Why divide by 2000 in the formula?
A: Dividing by 2000 converts pounds to tons (1 ton = 2000 pounds).

Q4: Can this calculator be used for asphalt?
A: Yes, this calculation method works for both tarmac and asphalt as they have similar densities and properties.

Q5: How accurate is this calculation?
A: The calculation provides a good estimate, but actual requirements may vary based on compaction, material variations, and site conditions.
