• Abstract:
  Corrosion of Florida’s bridge infrastructure has shown to be costly for FDOT, both due to the number of bridges and harsh environmental conditions across the State. While the mechanisms that describe corrosion within reinforced concrete bridge elements are well understood, the ability to limit corrosion in practice has led to many methods that aim to mitigate the effects of corrosion. These systems include durability-based design requirements for new bridges and rehabilitation efforts for existing bridges, summarized in this report. FDOT has implemented many of these systems on its bridges with varying degrees of success. This report also summarizes current FDOT design requirements and specifications regarding corrosion control for reinforced concrete bridge structures with a focus on substructure elements. A comprehensive study that compares multiple practices and systems across various Florida bridges has been undertaken. As a result, comparative data related to their performances have been compiled and analyzed. Without this information, it is challenging for the State to understand the benefits of its corrosion control measures and the life-cycle cost analysis of the systems. Therefore, this study aims to evaluate and compare multiple practices and systems used across the State in terms of durability, cost, and longterm performance. Although every corrosion prevention and control program described in this report will not be incorporated into this research, this study includes the most used measures, including concrete cover, supplementary cementitious materials, epoxy coating, and cathodic protection (metalized, impressed current, and galvanic).
