Asphalt Area Formula:
From: | To: |
Definition: This calculator converts the weight of asphalt in tons to the area it will cover in square feet based on depth and density.
Purpose: It helps construction professionals and paving contractors determine how much area a given quantity of asphalt will cover.
The calculator uses the formula:
Where:
Explanation: The tons are converted to pounds (×2000), then divided by the product of depth and density to get coverage area.
Details: Accurate conversion ensures proper material ordering, cost estimation, and project planning for paving projects.
Tips: Enter the asphalt weight in tons, depth in feet (default 0.25 ft = 3 inches), and density (default 145 lb/ft³ for hot mix asphalt). All values must be > 0.
Q1: Why 2000 in the formula?
A: There are 2000 pounds in 1 ton, which converts the weight from tons to pounds.
Q2: What's a typical asphalt density?
A: Hot mix asphalt typically weighs 145 lb/ft³, but this can vary from 140-150 lb/ft³ depending on mix design.
Q3: How does depth affect coverage?
A: Doubling the depth halves the coverage area - the relationship is inversely proportional.
Q4: What depth should I use for driveways?
A: Residential driveways typically use 2-3 inches (0.17-0.25 ft), while commercial pavements may require 4+ inches.
Q5: Does this include compaction factor?
A: The density value should account for compacted asphalt. Use laboratory density for precise calculations.
