Asphalt Tack Formula:
| From: | To: |
Asphalt tack coat is a thin layer of liquid asphalt applied between pavement layers to create a strong adhesive bond. It ensures proper bonding between old and new asphalt surfaces, preventing slippage and extending pavement life.
The calculator uses the simple formula:
Where:
Explanation: The formula calculates the total volume of asphalt tack required by multiplying the area to be covered by the application rate.
Details: Accurate tack calculation ensures proper bonding between pavement layers, prevents waste of materials, and helps maintain project budgets. Too little tack can lead to poor adhesion, while too much can cause bleeding and instability.
Tips: Enter the total area in square feet and the recommended application rate in gallons per square foot. Typical application rates range from 0.05 to 0.15 gallons per square foot depending on surface conditions.
Q1: What factors affect application rate?
A: Surface texture, temperature, and existing pavement condition all influence the optimal application rate. Rough surfaces typically require higher application rates.
Q2: How do I measure the area accurately?
A: Break irregular areas into smaller regular shapes (rectangles, triangles) and calculate each separately, then sum the total area.
Q3: Can this calculator be used for different units?
A: This calculator uses square feet and gallons. Convert other units to these measurements before calculation.
Q4: What's the typical coverage of tack coat?
A: One gallon of tack coat typically covers 100-200 square feet at standard application rates, depending on surface porosity.
Q5: When should tack coat be applied?
A: Tack should be applied when surfaces are clean and dry, just before placing new asphalt layers, typically in temperatures above 50°F (10°C).
