Abstract:Concrete bridge deck degradation has been observed in several bridges located in north Mississippi. In this study a survey was conducted to collect and document instances of deterioration in concrete bridges located throughout the State. The main causes of deterioration were observed to be corrosion, efflorescence, scaling and pop-outs. A guideline for identifying the basic causes of deterioration in the State of Mississippi and a guideline for the selection of suitable repair materials and methods were proposed. Preliminary work was conducted to evaluate the bond integrity of repair materials and concrete for a range of resin based materials and cement based materials which are used most commonly by MDOT maintenance staff.
