Development of the Crack Sealant Adhesion Test
Crack sealants are widely used in Texas to prevent water from entering into lower structural layers thereby extending pavement life. However, most current crack sealants have been reported to have a very short life mainly due to adhesive failures. Although adhesive failure is known to be the major failure mechanism very little attention has been paid to measuring this property in the laboratory. The main objective of this project was to develop a performance related adhesion test using TxDOTs Overlay Tester. In this report the crack sealant adhesion test protocol developed in year 1 of this study was finalized. The final test protocol includes a molding jig, a detailed sample preparation procedure, an adhesion test protocol, and criteria for interpreting the results. In this study 13 sealants (some of them have never been used in Texas) were evaluated following the proposed test protocol.
