Abstract:

Several types of instrumentation were installed by Texas Tech University on the Sierrita de la Cruz Creek bridge, located near Amarillo, Texas, for comparison of the performance of two spans with GFRP reinforcing bars in the top mat of the concrete deck to the performance of the other decks reinforced entirely with epoxy-coated steel (ECS). Short-term tests that were conducted included temperature measurements in the deck during and after a pour, crack mapping under no load and under static live loading, and deflection and strain measurements under static live loading. “Corrosion bars” and different types of “witness bars” were also placed in the deck for possible long-term studies in the future. The GFRP-reinforced concrete decks showed very good short-term performance. Only temperature and shrinkage cracks were observed, even under load, and the stiffness was as great or greater than predicted for an 8-inch deck thickness.
