FHWA Building Bridges Faster, Safer, Cheaper SHRP2 advances structures solutions to nationwide implementation by Matthew J. DeMarco, Federal Highway Administration The Federal Highway Administration (FHWA), in partnership with the American Association of State Highway and Transportation Officials (AASHTO), is responsible for implementing the tools and products delivered by the Transportation Research Board (TRB) under the Second Strategic Highway Research Program (SHRP2). SHRP2 adheres to the principles of the original SHRP model—a focused, time-constrained, management-driven program designed to complement existing research programs. And like SHRP, with technical product development administered by TRB and national implementation co-administered by FHWA and AASHTO, SHRP2 addresses many of the most pressing needs related to the nation’s highway system including • the high toll taken by highway deaths and injuries, • an aging infrastructure, and • congestion stemming from inadequate capacity. As such, the over-arching goals of the program remain to “Save Time—Save Money—Save Lives.”1 To expedite adoption of SHRP2 innovations and solutions, the partners launched the SHRP2 Implementation Assistance Program (IAP) in early 2013 to provide direct financial and technical support to early adopters of SHRP2 products. The collaborative approach that drove SHRP2 research—including nearly 150 state department-of-transportation-supported research efforts—is being carried through into implementation to ensure the needs of potential users are incorporated into every stage of technology transfer. Currently in full swing, the assistance program has thus far delivered 34 products through four IAP rounds, engaging all 50 states in over 250 technology deployment projects. Two more assistance offerings in 2015 will deliver 11 new products, as well as additional awards for several products previously offered. Of the SHRP2 solutions delivered to date, six products under the Renewal focus area support improved bridge design, construction, and maintenance, including selection of geoconstruction technologies, bridge design for accelerated and long-life construction, concrete element nondestructive inspection methods, and construction performance specifications. These products are described in more detail in the following sections. R02—GeoTechTools GeoTechTools is a comprehensive, web-based application containing information on more than 50 geoconstruction technologies applicable to transportation infrastructure, including bridge foundations, abutments, and approach embankments. The two primary components of this comprehensive toolbox are a Catalog of Technologies and a Technology Selection Assistance System. GeoTechTools was developed to assist engineers involved in project development, scoping, and/or the execution of highway projects make more informed decisions on geotechnical issues to reduce risk and minimize construction surprises. R04—Innovative Bridge Designs for Rapid Renewal The Innovative Bridge Designs for Rapid Renewal: ABC Toolkit includes design standards, examples, and standard drawings for complete prefabricated bridge systems, and proposes specification language for accelerated bridge construction. The R04 focus is on providing accelerated bridge construction (ABC) options for small-to-medium “bread-and-butter” bridges. It also complements the national goals of the Everyday Counts ABC program for prefabricated bridge element systems (PBES), slide-in bridges, and geosynthetic reinforced soil/ integrated bridge systems (GRS-IBS).
