Trackless Tack Bond Strength Performance

In emulsion asphalt and non-tracking tack materials, bond strength significantly influences bituminous pavement performance. Kentucky Transportation Cabinet (KYTC) bituminous pavements show evidence of debonding. Debonding has also occurred on resurfacing projects. Non-tracking tack is a new material that is used as tack. Its adoption has raised several questions related to application rate, seasonal limitations, and equipment requirements. Leveraging previous work on the effect of bond strength on bituminous pavement performance, project activities will focus on implementing research, obtaining data on Kentucky pavements, and developing recommendations related to bond strength.
