Abstract
Recently, corrosion damages on upper surface of orthotropic steel deck have been found during the pavement repair work in urban expressway. Thus, a simple repair method for corrosion damages is strongly required to be done during the pavement repair works. Therefore, the authors focused on the bond repair method using patch plates of steel or CFRP. However, in pavement repair, asphalt with temperature of 200°C or more is paved on the upper surface of orthotopic steel deck. Accordingly, adhesive used for bond repair is also exposed to high temperature by asphalt paving. In this study, to clarify the effect of high temperature to the debonding strength of patch plate, steel plates adhesively-repaired with patch plate exposed to high temperature during curing were bending tested. As a result, debonding strength did not decreased by exposing the high temperature during curing of adhesive.
