For large areas, the application rate is determined by the placement of a given quantity of an asphalt material over a known area. The rate is calculated using the gallons (liters) indicated by the volume indicating device on the distributor, the known length of the distributor run, and the measured width that is covered.

Proper application of tack coat is a key ingredient to quality asphalt paving. A good tack coat provides the necessary bond to underlying layers, maximizes the strength of the pavement structure and helps ensure long-lasting performance. On the other hand, the lack of a good tack coat or poor adhesion can quickly lead to premature hot mix failures.
