Thin bondage overlays are used to repair concrete bridge decks in some parts of the world. Repair work using a thin bonded overlay consists in removing the damaged concrete from the slab's surface and replacing it with a thin concrete overlay. The quality of the bond between the overlay and the substrate is important because it prevents the ingress of chlorides and contaminated water into the bridge deck and provides a new wearing surface on the bridge deck. A good bond ensures that the substrate and overlay react compositely.
Pull off tester may verify proper bonding of overlays to bridge decks, ensuring structural integrity. Before measuring, the measuring procedure must be prepared. First of all, the user must cut into the test surface with a core drill so that the break can occur over the defined circular surface. Then, the test disc has to be attached to the test surface, using an adequate adhesive. After this, the user has to wait until the required adhesive strength is reached.
