About the research

Abstract:

With the assistance of the Iowa Department of Transportation (DOT) and three centers at the Institute for Transportation (InTrans) at Iowa State University, Buchanan County, Iowa was awarded a Federal Highway Administration (FHWA) Innovative Bridge Research and Deployment (IBRD) Program grant to help construct and evaluate a replacement bridge that used innovative concepts to increase the bridge’s durability, while also striving to construct the bridge without the use of a traditional overhead crane, making the bridge system an attractive alternative for county workforces and minimizing disruption to the traveling public.

The innovative concepts utilized for this bridge included geosynthetic-reinforced soil (GRS) abutments, high-performance concrete (HPC) with lightweight fine aggregates (LWFAs) for internal curing, and a cast-on-site concrete box-beam superstructure.

Conclusions from the project included the following:
