Performance Evaluation of Tack Coat Materials

The main purpose of this project is to assess the bond strength of tack coat materials applied under a variety of conditions, including tack coat material, application rate and uniformity, moisture and temperature, and pavement layer types. To evaluate the bond strength, the research team utilized direct shear and rotational shear tests conducted in controlled laboratory conditions. The rotational shear test was also utilized in the field for one active construction project and one controlled field test section. The results of the study will provide WisDOT officials with the data necessary to make informed decisions concerning the need for the continuation of the current tack coat specifications or to develop new or modified specification requirements.
