• Abstract:
  Glass Fiber Reinforced Polymer (GFRP) dowel bars were installed on one new construction project and two dowel bar ; retrofit projects to evaluate the performance of this type of dowel bar in comparison to steel dowel bars installed on the same ; contracts. The primary data collection site (I-82, Yakima River Br. Vic. to Granger) included 67 joints retrofit with GFRP ; dowels and an equal number of epoxy coated doweled joints that serve as the control section. ; Falling weight deflectometer (FWD) testing will be used to evaluate the load transfer efficiency (LTE) of the two types of ; dowel bars. Periodic coring of the concrete at the joints is also planned to examine the condition of the GFRP and epoxy ; coated dowels. ; Post-installation FWD testing of the primary data site revealed that the average LTE of the joints retrofit with epoxy ; coated dowel was higher than the joints retrofit with the GFRP dowels and that the difference was statistically significant. Preinstallation ; FWD testing showed no difference in the LTE of the joints in the areas where the GFRP and epoxy coated dowels ; were installed.
