In this study a procedure has been developed to evaluate the structural condition of pavements using Road Rater deflection measurements. These procedures compare actual field deflections with deflections calculated by the Chevron N-Layer linear elastic computer program. The results obtained from these procedures are the layer moduli of the pavement materials. Procedures have been developed for asphaltic concrete pavements and composite pavements, including broken and non-broken concrete layers. This report also contains a comparison of structural overlay determined using the results of the new procedure, with overlays calculated using results from the 2-3 Projected procedure currently used by the Pavement Management branch of the Kentucky Transportation Cabinet. A users manual from the computer programs developed during this study is included in the appendix of the report.
