Validation of Probability-Based Chloride-Induced Corrosion Service-Life Model

A major problem in North America is bridge deck deterioration due to chloride-induced corrosion. Primarily, chlorides are the result of bridge deck surface deicing salt applications. Fick's second law of diffusion is typically used to model chloride ingress into concrete. A deterministic approach to chloride diffusion estimation has been taken by previous service-life models. A service-life model that incorporates diffusion parameters' probabilistic nature through Monte Carlo statistical resampling techniques was developed, however, through a recent project. Using data from ten bare steel bridge decks constructed between 1965 and 1968 in Virginia, the probabilistic service-life model is validated by the authors.
