1. What is the Asphalt Yield Equation?

The Asphalt Yield Equation calculates the volume of asphalt concrete that can be produced from a given weight of material, based on its density. It helps in estimating the coverage and material requirements for paving projects.

2. How Does the Calculator Work?

The calculator uses the asphalt yield equation:

Where:

• \( Tonnage \) — Weight of asphalt material in tons
• \( Density \) — Density of asphalt concrete in pounds per cubic yard (lb/cu yd)
• 2000 — Conversion factor (pounds per ton)

Explanation: The equation converts the weight of asphalt from tons to pounds, then divides by the density to determine the volume in cubic yards.

3. Importance of Asphalt Yield Calculation

Details: Accurate yield calculation is essential for project planning, material ordering, cost estimation, and ensuring proper coverage in asphalt paving projects.

4. Using the Calculator

Tips: Enter tonnage in tons and density in lb/cu yd. Both values must be positive numbers. The result will be in cubic yards.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density range for asphalt concrete?
A: Asphalt concrete density typically ranges from 140-160 lb/cu ft, or about 3780-4320 lb/cu yd.

Q2: Why is 2000 used in the formula?
A: 2000 represents the number of pounds in one ton, used to convert tonnage to pounds for consistent units.

Q3: Can this calculator be used for other materials?
A: While the formula is general, the density values would need to be adjusted for different materials beyond asphalt concrete.

Q4: How accurate is this yield calculation?
A: The calculation provides a theoretical yield. Actual field results may vary based on compaction, material consistency, and other factors.

Q5: What if I have density in different units?
A: Convert your density to pounds per cubic yard before using the calculator for accurate results.
