How is the rate of application for tack coat calculated?

The calculation of the rate of application for a tack coat is determined by taking the total gallons of tack coat applied and dividing it by the square yards of surface covered. This method provides a clear metric that indicates how much tack coat is being used per unit area. The square yards measurement establishes a standard unit of area, making it easier to understand the application rate in relation to the surface being treated.

Using total gallons applied allows for a direct measure of the liquid material used, whereas expressing that amount relative to the area ensures the tack coat is applied evenly and in an effective amount. This is particularly important in roadway applications to promote adhesion between layers of asphalt and improve the overall durability of the road surface.

While other methods of calculating might appear relevant, they do not specifically reflect the relationship between the amount of material applied and the area being treated, which is critical for ensuring proper application standards in roadway construction and maintenance.
