• Abstract:
  The sponsored research merges materials science and engineering methods for corrosion science with structural engineering approaches to bridge inspection and assessment to generate and implement a corrosion prediction model for bridge inspection and asset management systems. We built on prior work identifying the progression of corrosion as a function of local chloride ion concentration (Cl-). The project includes lab-based objectives that establish thresholds of local Cl- for corrosion formation and impacts of galvanic coupling, sandblast cleaning, and Zn-based coating systems on corrosion rates. Through accelerated corrosion testing, polarization testing, and characterization of samples, a corrosion prediction model will be built for field-use. Field-based objectives included comparison of lab-based data to field collected samples. The project is highly relevant to New England bridges where chlorine exposure from water and de-icing salts are common.
