Condition Rating of Bridge Decks with Fuzzy Sets Modeling for SF-GPR Surveys

Highway agencies monitor the condition of thousands bridge decks every year. Even though Ground Penetrating Radar (GPR) has been used in bridge-deck evaluation, Step-Frequency GPR (SF-GPR) provides advanced assessment yet requires extensive and complex post-processing analysis. An SF-GPR analysis system was recently developed for monitoring all state Maryland. The objective this study to develop a deck rating approach using fuzzy sets modeling on data membership functions needed reflect score categories similar those considered National Bridge Inventory (NBI) database uniformity. Thus, built considering nine functions. overall leading each states based both physical condition-related parameters as obtained from is presented herein, along with two examples. proposed novel can be possible adoption elsewhere where systems are used.
