Asphalt Weight Formula:
From: | To: |
Definition: This calculator estimates the weight of asphalt needed based on area in square feet, depth, and material density.
Purpose: It helps construction professionals and homeowners determine how much asphalt is required for paving projects.
The calculator uses the formula:
Where:
Explanation: The area multiplied by depth gives volume, multiplied by density gives weight in pounds, divided by 2000 converts to tons.
Details: Accurate asphalt weight estimation ensures proper material ordering, cost control, and project planning.
Tips: Enter the area in square feet, depth in feet, and density (default 145 lb/ft³ for asphalt). All values must be > 0.
Q1: What's the standard density for asphalt?
A: Hot mix asphalt typically weighs 145 lb/ft³, but can range from 140-150 lb/ft³ depending on mix.
Q2: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 3 inches = 0.25 feet).
Q3: Why divide by 2000 in the formula?
A: There are 2000 pounds in 1 ton - this converts the weight from pounds to tons.
Q4: Does this account for compaction?
A: The density value should reflect compacted asphalt. For loose asphalt, use a lower density (about 130 lb/ft³).
Q5: How much extra should I order?
A: Consider adding 5-10% to the calculated weight for waste, uneven surfaces, and compaction variance.
