| The first North American Ductal bridge wins a 2006 PCA award The Wapello County Mars Hill Bridge (the first Ductal / UHPFRC (Ultra-High Performance, Fiber-Reinforced Concrete) highway bridge in North America) is winner of a 2006 PCA (Portland Cement Association) Bridge Award. This prestigious award will be presented to Vic Perry, VP/GM, Ductal, on behalf of the winning team, at the ACI (American Concrete Institute) Fall Convention on November 5th, in Denver. After 5 years of collaborative R&D between the Federal Highway Administration (FHWA), the Iowa Department of Transportation, Iowa State University/Bridge Engineering Center and Lafarge North America, this innovative bridge provides a significant step towards "The Bridge of the Future". With a single-span, 3-beam cross section, it has three 110-foot Ductal girders with no rebar for shear stirrups. The unique girders were produced by Lafarge AC&A/ Precast in Winnipeg, Manitoba, Canada and delivered to the site in Iowa. The PCA biennial competition recognizes excellence in the design and construction of concrete bridges. The 2006 program attracted 79 entries from Canada and the United States. write your comments about the article :: © 2006 Construction News :: home page |
