Abstract:

As part of a national initiative sponsored by the Federal Highway Administration (FHWA) under the Innovative Bridge Research and Construction (IBRC) program, the Colorado Department of Transportation (CDOT) incorporated an innovative and emerging technology on the Parker road/I-225 interchange reconstruction project. For the first time in its history, CDOT put to work carbon fiber reinforced polymer (FRP) in precast bridge deck panels in place of steel tendons. Glass FRP was used as mild reinforcement in conjunction with carbon FRP and also in the construction of a bridge rail. FRP materials are highly resistant to corrosive action of chloride and have a higher strength to weight ratio than steel tendons. The primary objective of this study was to validate the mechanical properties and the performance of carbon and glass FRP bars as reinforcing agents for bridge decks at the I-225 and Parker road interchange. Included in this report is an overview of existing literature on FRP reinforcement, evaluation of the bond strength of the FRP bars using pullout tests, and load testing of three prestressed panels and two composite slabs to failure.
