What is the critical aspect of traffic management when using tack?

The critical aspect of traffic management when using tack is to keep traffic off tack until it breaks. When tack is freshly applied, it remains quite tacky and can be easily disturbed or damaged by traffic. Keeping vehicles off the tack ensures that the bonding properties of the tack are preserved, which is essential for the proper adhesion of the asphalt layer that will be placed on top. If traffic passes over the tack before it has set or 'broken', it can lead to poor bonding, resulting in potential failures in the asphalt layer.

This understanding emphasizes the importance of maintaining a controlled environment during the paving process. It helps to ensure that the asphalt bond is effective, ultimately contributing to the durability and longevity of the paved surface. Inadequate management of traffic over the freshly applied tack can compromise the overall quality of the work, necessitating additional repairs or corrections later.

Maintaining this careful balance with traffic management is crucial to achieving optimal results in asphalt paving.
