Abstract:Cast-in-place bridges using normal concrete have been commonly used in the state of Alabama for short-span bridges. Even though their performance is satisfactory after construction and opening to traffic, this construction method requires a significant amount of construction time and on-site labor compared to the use of precast systems. The Accelerated Bridge Construction (ABC) method is a technique that is becoming increasingly common in the United States. It involves the use of large prefabricated bridge elements and systems (PBES) in bridge construction, providing improvements in safety, quality, durability, social costs, and environmental impacts.1 PBES comprises a deck, beam, column, pier, abutment, wall, and other miscellaneous elements that are prefabricated in factory settings, transported and assembled onsite, becoming part of the constructed bridge. Figure 1 shows typical PBES members used in ABC technology being installed onsite.
