In Step 1 for figuring the tack spread rate, what should you find first?

To determine the tack spread rate effectively, the first step is to find the length of the tack shot. This is crucial because the length contributes to calculating the total area that will be covered by the tack coat. By identifying how long the tack shot will be applied, you can better gauge the required amount of material for the project.

Once you have established the length, you can use it alongside other dimensions, such as the width of the tack shot, to ultimately determine the total area. This is essential for accurate calculations in paving operations, ensuring that the right amount of tack is applied for effective adhesion between layers.

Knowing the length first lays the groundwork for further calculations, including the total weight of the tack and its spread rate per unit area. While the other factors, such as the total weight of the tack or temperature, are important in the overall process, they come into play after you have established the dimensions of the tack shot.
