Abstract: This research studied the relationship between Oregon national bridge inventory (NBI) data as well as additional design/detailing variables and concrete highway bridge deck performance. Cox proportional hazards regression ...

Abstract: This study applied a heterogeneity-based survival analysis to determine significant contributing factors to a bridge deck’s time-in-condition rating (TICR) by condition rating (CR) group: high CR, medium CR, and low CR. ...

Abstract: This study employs a random parameters binary logistic regression (LR) to characterize the impact of environmental and structural parameters on concrete highway bridge deck deterioration nationwide. Two specific gaps in ...
