One corrosion-resistant alternative to steel dowel bars in rigid, concrete highway pavements is non-metallic dowel bars. Steel and fiber composite materials were tested in the laboratory. Fatigue and static testing were performed on full-scale concrete pavement slabs supported by a simulated subgrade, including a single transverse joint. Single dowels cast in concrete underwent static shear testing using a test method developed previously, and test results from elemental and full-scale tests were compared and related. The behavior of full-scale specimens with both steel and fiber composite dowels placed at test joints was monitored during several million load cycles, which simulated truck traffic at a transverse joint. Performance of the fiber composite dowels indicated that they are at least as effective as steel dowels in resisting degradation of load transfer efficiency under cyclic loading.
