At what temperature should the tack be heated?

The ideal temperature range for heating tack is between 250 to 300°F. This temperature range is crucial because it ensures that the tack coat can effectively adhere to both the existing pavement and the new asphalt being placed. Heating the tack coat to this temperature promotes optimal viscosity, which enhances its ability to spread evenly and bond effectively when applied.

At temperatures below this range, the tack may not adequately bond, creating issues with adhesion and potentially leading to premature failure of the pavement structure. Conversely, heating the tack coat above this range could cause it to degrade or become too thin, compromising its adhesive properties. Thus, ensuring the tack is heated within the specified range is essential for high-quality asphalt paving.
