Abstract:This report reviews the research on data and metrics related to concrete bridge deck performance for the state of Oregon. With guidance from the literature and ODOT personnel, two datasets were created with data currently available through ODOT and the NBI to evaluate concrete bridge deck performance. Using these datasets, a survival analysis was performed to predict concrete bridge deck performance and identify the parameters that drive bridge deck deterioration. To improve concrete bridge deck performance monitoring in the future, a list of parameters that can be collected by ODOT was identified by combining the results from the survival analysis with the responses from a survey on bridge deck performance.
