What is the first step when calculating the tack spread rate related to the distributor?

When calculating the tack spread rate related to the distributor, the first step involves identifying the length of the tack shot. This is essential because the tack coat must be applied over a specific area to ensure adequate bonding between the existing surface and the new layer of asphalt. Knowing the length allows producers to calculate the total volume of tack needed based on the defined width and desired spread rate.

By determining the tack shot length, operators can effectively plan the amount of material that will be required for the job, ensuring that there is neither too much nor too little applied. This step sets a solid foundation for the subsequent calculations, which will consider factors like gallons required at a certain temperature, the correction factor for various conditions, and the necessary width of the application. Each of these elements builds on the initial understanding of the tack shot length, underscoring its importance in the overall process.
