Asphalt Calculation Formula:
| From: | To: |
The Asphalt Calculator Square Yards is a tool that estimates the amount of asphalt needed for a paving project based on area in square yards and desired thickness in inches. It calculates the total weight in tons required for the job.
The calculator uses the asphalt calculation formula:
Where:
Explanation: The formula calculates the volume of asphalt needed and converts it to weight using standard density values for asphalt mix.
Details: Accurate asphalt quantity calculation is crucial for project planning, budgeting, material ordering, and ensuring you have enough material to complete the paving job without excess waste or shortages.
Tips: Enter the area in square yards and desired thickness in inches. Make sure measurements are accurate for the best results. Typical asphalt thickness ranges from 2-4 inches for driveways and 4-8 inches for roads.
Q1: Why use 110 pounds per square yard per inch?
A: This is the standard density for hot mix asphalt (HMA) used in most paving projects, though actual density may vary slightly based on mix design.
Q2: What's the typical thickness for different applications?
A: Residential driveways: 2-3 inches, Commercial parking: 3-4 inches, Heavy traffic roads: 4-8 inches, with base layers adding additional thickness.
Q3: How do I convert square feet to square yards?
A: Divide square feet by 9 to get square yards (since 1 square yard = 9 square feet).
Q4: Does this account for compaction?
A: The calculation uses compacted asphalt density, so it accounts for the final compacted volume after installation.
Q5: Should I order extra asphalt?
A: It's recommended to order 5-10% extra to account for waste, uneven surfaces, and compaction variations.
