Pavement Evaluation of the Concrete Tie-bars and Dowel Baskets on Irvin Cobb Drive, US 60, McCracken County, KY
A 1500 Mhz. ground coupled, ground penetrating radar antenna was used to identify both the horizontal alignment and the vertical displacement of the concrete tie-bars and the transverse joint dowel bar assembles on a Portland-Cement-Concrete-Pavement (PCCP) on US 60 in McCracken County, Kentucky. Approximately 5 lanes miles of PCCP were evaluated using the 1500 Mhz. ground coupled antenna. Results indicate that only one transverse dowel basket out of an approximate total of 1,760 were within 4.17 inches of the pavement surface. Seven transverse dowel baskets were misaligned four inches or greater from the location of the sawed joint. These areas represent 0.45 percent of the total transverse joints on the project. The ground penetrating radar results also indicated there were no areas along the longitudinal joint where the tie-bars were either too close to the pavement surface or missing.
