The experimental joint described in this paper involves the use of a new type load transfer set-up which was developed by the Oxford Manufacturing Company, Oxford, Indiana, and produced by the Reynolds Metals Company. The producers designed this apparatus on the assumption that the present joints used in concrete pavement construction are not adequate. For example, from the standpoint of load bearing, the dowel bars which theoretically carry the load from one slab to the other are not sufficient in that the very shape of the bars (circular) allows only a limited bearing surface. In order to eliminate the rusting which often renders the dowel bars useless, this apparatus is made of aluminum. Two of these experimental joints were laid early last fall in Paducah, Kentucky, under the supervision of the Division of Construction.
