Webinar on Solutions for Aging Low-Volume Road Bridges

The Transportation Research Board (TRB) is conducting a webinar on Solutions for Aging Low-Volume Road Bridges that will illustrate ways to repair old bridges, close bridges, and find alternate structures or routes that adhere to budgetary restraints. Presenters will discuss several options, including salvaging old parts, using accelerated bridge construction and modular construction techniques, building … Read more

Learn about Ultra-High Performance Concrete for Prefabricated Bridge Element Connections

Ultra-high performance concrete (UHPC) can be used to create simple, strong, long-lasting connections needed for successful construction using prefabricated bridge elements (PBEs). Compared to many solutions in current use, UHPC allows for small, simple-to-construct connections that require less volume of field-cast concrete and do not require post-tensioning. The mechanical properties of UHPC also allow for redesign … Read more

FHWA TechNotes on Bridge Construction Using Prefabricated Elements

FHWA’s Bridge Engineering Research Team in the Office of Infrastructure Research has released two new TechNotes focused on bridge construction using prefabricated elements.  Prefabricated bridge elements are assembled then connected onsite during bridge construction, and these connections often include the use of field-cast grouts.    These two TechNotes (FHWA-HRT-16-080 and FHWA-HRT-16-081) provide insight into test methods, key … Read more
