Project Objectives

The objective of this project is the development of pultruded Glass Fiber Reinforced Polymer (GFRP) panels as stay-in-place (SIP) formwork and internal reinforcement for the rapid construction of corrosion-free concrete bridge decks.

Project Abstract

The impact of economic and social costs typically associated with bridge replacement presents the need to develop structural systems that can be rapidly installed, in addition to providing adequate durability under harsh environmental and loading conditions. This research project deals with the development of large-scale, pultruded Glass Fiber Reinforced Polymer (GFRP) panels as stay-in-place (SIP) formwork and internal reinforcement for the rapid construction of corrosion-free concrete bridge decks. The technology will be implemented in a pilot field application in the U.S.

Anticipated Benefits

Rapid construction of bridge decks thanks to the implementation of FRP composite technologies.
