[0002] If the adhesion between the bridge deck and the pavement layer is insufficient, or the adhesion between the asphalt concrete layers is poor, shear failure is very likely to occur between the bridge deck pavement layers under the action of vehicle loads. Therefore, it is necessary to conduct a large number of tests on the bonding strength of the bridge deck, and an adhesion testing device is needed.
