1. What is an Asphalt per Sq Ft Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W_{sf} = \frac{D \times \rho}{12} \]

Where:

\( W_{sf} \) — Weight per square foot (lb/ft²)
\( D \) — Thickness of asphalt (inches)
\( \rho \) — Density of asphalt (lb/ft³)

Explanation: The formula converts thickness from inches to feet (dividing by 12) and multiplies by density to get weight per square foot.

3. Importance of Asphalt Weight Calculation

Details: Accurate weight estimation is crucial for structural support requirements, truck load calculations, and project cost estimation.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's a typical asphalt density?
A: Hot mix asphalt typically weighs about 145 lb/ft³, but 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 foot.

Q3: Why calculate weight per square foot?
A: It helps determine total project weight when multiplied by area, and is useful for structural load calculations.

Q4: How do I convert this to total tons?
A: Multiply weight per sq ft by total area (in sq ft), then divide by 2000 to get tons.

Q5: Does this account for compaction?
A: The density value should reflect the compacted density of the asphalt mix being used.
