Tack coats are used to bond pavement layers together, and if the proper materials are used, handled and applied correctly, they will provide an excellent bond between layers, which will lead to good long-term performance of the pavement.

Tracking of tack coat materials occurs when the tack material sticks to the tires of construction vehicles that drive over the tacked surface. This can be a major problem from a performance, safety and aesthetics perspective and continually needs to be addressed. Understanding the causes of tracking is key to identifying the potential solutions.
This webinar will focus on the primary causes of tracking and steps that can be taken on paving projects to minimize or prevent tracking from occurring.
