2320 Service Life of Bridge Deck Repairs using Flood Coats

The purpose of this research is to address the premature deterioration of bridge decks due to a combination of shrinkage-induced cracking, cyclic loading from traffic, and chemical ingress from deicing salts. These factors not only reduce the structural service life of bridge decks but also impose significant maintenance costs on state infrastructure budgets. A widely used technique to address such deterioration is the application of epoxy or methyl methacrylate (MMA) flood coats. These materials are designed to penetrate surface cracks, seal voids, and prevent ingress of moisture and salts. However, concerns remain regarding the long-term performance of these coatings due to their brittleness, temperature sensitivity, and limited bonding durability under cyclic environmental and loading conditions. This study proposes a comprehensive investigation into the service life and performance characteristics of conventional epoxy and MMA coatings and two emerging advanced materials: (a) alumina nanoparticle (ANP)-modified MMA, and (b) a ceramic polymer coating known as CeramycGuard.
