Understanding the implication of climatic variation have become important issues for infrastructure maintenance planning. Corrosion of concrete is a possible occurrence of changing climate, which mostly induced by several important environmental factors such as change in CO2, temperature and relative humidity. According to the IPCC, the Northeastern United States is particularly vulnerable for extreme precipitation, rise in temperature and relative humidity. During winter season Massachusetts, New Hampshire, and New York are the highest road-salt user states for snow melt, with Massachusetts the highest at 20 tons/lane-mile/yr; according to National Research Council study. Therefore, chloride induced corrosion can be critical in longer period particularly for road infrastructures in Boston Metropolitan Area (BMA). Consequently, the current study is focusing on estimating corrosion damage risk for BMA infrastructures under a changing climate that includes both carbonation and chloride induced corrosion. A probabilistic statistical model is being prepared to estimate the climate impact risk of the superstructures utilizing cement concrete under extreme emission scenario. Minimum concrete cover thickness (mm) and diffusion coefficient reduction of deleterious substances will be considered outcome from the model. The outcome will be compared by the existing ACI concrete design depths for building and AASTHO allowable chloride penetration resistance for concrete pavements. Later, effectiveness of climate change adaptation scenarios for modern and existing building, bridges and other concrete infrastructure will be assessed. Expected results from this study are to evaluate how the carbonation and chlorination induced corrosion damage risks will affect the long term infrastructure sustainability of BMA.
