COMPOSITE REPAIR OF RAILROAD CROSSTIES THROUGH THE PROCESS OF SHEAR SPIKING

The document reports on an investigation into the effects of Z-spiking with fiber reinforced polymer (FRP) rods have on the flexural stiffness and repair of deteriorated railroad crossties. The tests were conducted as a pilot study for repairing full scale bridges. The report presents results of the study that show an increase in flexural stiffness when shear spikes were inserted into the crossties. The results also indicate that the use of FRP shear spikes as a reinforcement method dramatically increased the flexural stiffness of the crossties and helped to offset the deterioration from decay. Additionally, the shear spikes and epoxy resin show a strong possibility for repairing decay voids present on the surface of the deteriorated crossties as well as their interior portions.
