Abstract:This report describes research performed by the South Dakota Department of Transportation to investigate the problem of dowel bar misalignment in PCC pavements. Over 400 dowel bars from three (3) construction proje°cts were inspected and compared to the dowel bar alignment specifications. This study found that the dowel bars tended to conform to the alignment specifications even though. in the opinion of the researcher , the specifications were too rigid. It was noted that sawing of the contraction joint was the governing factor for the longitudinal displacements. Although no pavement distress was observed in areas containing dowel bar misalignments, it should be noted that only two (2) years bad passed between project construction and the field survey. It is the opinion of the researcher that this is insufficient time for pavement distress to manifest itself since even undoweled PCC pavement may not show distress or faulting for 5 years or more.
