More Choices for Connecting Prefabricated Bridge Elements and Systems (PBES)

Prefabricating bridge elements and systems (PBES) offers major time savings, cost savings, safety advantages, and convenience for travelers. According to the Federarl Highway Administration (FHWA), the use of PBES is also solving many constructability challenges while revolutionizing bridge construction in the US. In the past decade, innovative PBES connections have been evolved and many of these connections used Ultra-High performance concrete (UHPC). UHPC has superior mechanical properties and durability. However, some of the limitations associated with UHPC wide spread use include: the very expensive price tag, the expertise needed to work with UHPC, it is labor intensive, and most of the robust mixes are currently proprietary. Several state departments of transportation (DOTs) see the proprietary nature of UHPC leads sometimes to sole-sourcing and in turn, bidding issues. Thus, there is a growing interest nowadays to find other alternatives and choices for PBES connections. The goal of this project is to identify potential alternatives to replace UHPC in PBES and accelerated bridge construction (ABC) seismic and non-seismic connections. These alternatives can include special or advanced grout, polymer concrete, fiber concrete, etc. One selected material or alternative will be tested for at least two different PBES or ABC connection types.
