Paper from Iowa State University on "Alternative Dowel Bars"

ABSTRACT
Alternative dowel bars for joints have been undergoing investigation at Iowa State University (ISU). The alternatives include size, shape and material parameter changes from the conventional 1.5-in. diameter, 18-in. long steel dowels currently employed in joints of pavements, bridge approaches and other locations where load transfer is needed but longitudinal movement must be accommodated. Alternative materials from the conventional steel dowel have been investigated. Among these alternative materials, fiber reinforced polymer (FRP) has been give considerable attention. FRP is considered a high candidate to replace steel in those areas where corrosion is of concern. The FRP allows for the slip that is needed but provides for a non-corrosive dowel bar. In addition to alternative materials that have been investigated, alternative shapes have been tested at ISU. Elliptical, hollow, and other shapes have been tested in the Structural Engineering Laboratory. The tests include elemental behavioral parameter tests, and full-scale pavement slabs subjected to up to 10 million cycles of load. This paper will focus on the structural behavior of the dowel bars utilized in conventional joints of a small gap.
