Field Testing Evaluation of Laurel Hill Creek Bridge
Bridge deck deterioration has been recognized by highway agencies as one of the most complex problems that plagues United States transportation infrastructures (Gangarao, 1999). Federal and state transportation agencies have turned to investigating non-conventional advanced materials to help solve the deterioration problems of highway infrastructure, especially bridge decks. Fiber reinforced polymer (FRP) composites are one of the advanced materials considered to have high potential for use in bridge deck repair and replacement. Advances in manufacturing and design of FRP composites have lead to the production of bridge deck modules that can be used as temporary or permanent replacements for bridge decks (Gangarao, 1999). The Constructed Facilities Center of West Virginia University (CFC-WVU), in cooperation of Pennsylvania Department of Transportation (PENNDOT) constructed an FRP composite deck-steel stringer bridge (Laurel Hill Creek) in 1998 in Somerset County, Pennsylvania. Shortly after construction, CFC-WVU had initiated monitoring the in-service performance of the FRP composite deck bridge over a three-year period. The FRP composite deck stiffened by steel stringers on the Laurel Hill Creek Bridge was subjected to actual truckloads, and also to real environmental loads. Thus, Laurel Hill Creek Bridge provides an excellent opportunity to evaluate its performance of bridge under static and environmental loads. This report presents several technical details on the construction and performance evaluation of Laurel Hill Creek Bridge. The performance evaluation entails: (1) load testing and evaluation of strains and deflections induced under HS-20 loading conditions; (2) degree of structural composite action between the FRP deck and steel stringers; (3) transverse load distribution factor; (4) performance of deck-to-beam connections, and (5) deck deformations.
