• Abstract:
  Since 1983, TDOT has absorbed approximately 3,500 miles of former county roads into its system. The composition and structural capacity of a large portion of these road ways is unknown, except for new overlays that have been constructed since that time. The objective of this study is to utilize ground penetrating radar (GPR)technology to determine the pavement composition and structural capacity of these roads. In this study, GPR is used to obtain pavement layer thickness and identify layer structure for 264 TN state routes. The GPR data was validated using core test results at selected points on the roadway segments. Information from GPR data is then augmented by deflection data obtained from falling weight deflectometer (FWD) tests to determine structural capacity and overall pavement conditions of these roadways.
