Abstract:The members of the Iowa Concrete Paving Association, the National Concrete Pavement Technology Center Research Committee, and
the Iowa Highway Research Board commissioned a study to examine alternative ways of developing transverse joints in portland
cement concrete pavements. The present study investigated six separate variations of vertical metal strips placed above and below the
dowels in conventional baskets. In addition, the study investigated existing patented assemblies and a new assembly developed in Spain
and used in Australia. The metal assemblies were placed in a new pavement and allowed to stay in place for 30 days before the Iowa
Department of Transportation staff terminated the test by directing the contractor to saw and seal the joints. This report describes the
design, construction, testing, and conclusions of the project.
