Personnel from the University of Kentucky Transportation Research Program (KTRP) were requested by the Tennessee Transportation Center to conduct a demonstration project concerning the collection and use of deflection data (Road Rater) for evaluation of the existing condition of flexible pavements for use in overlay design. The demonstration project involved using the Road Rater to collect deflection data on specific pavement sections selected by the Tennessee Department of Transportation (TDOT). Deflection data were evaluated in a way that provides input parameters for an overlay design procedure (see Appendix A). The Kentucky overlay design procedure was used to make recommendations concerning overlay designs. Tennessee Department of Transportation personnel accompanied KTRP personnel in the field and were instructed on the complete testing, evaluation, and design procedures.
