Analysis of Load Responses in PCC Airport Pavement
To understand what actually happens in the pavement as aircraft wheels pass by, pavement deflections and strains were plotted against time using field test data collected at Denver International Airport. Shapes of the response-versus-time curves were analyzed in detail, and the locations of the maximum responses are shown graphically.According to the analysis, maximum deflections occur between the dual wheels, whereas maximum strains occur beneath one of the wheels. The plots also show clear reversals in the longitudinal strain-versus-time curves. These strain reversals were carefully investigated and some interesting results were obtained. A method to compute the deflection-based load transfer efficiencies was developed. The computation further showed that the load transfer efficiency for dummy joints is direction dependent, and that the load transfer efficiency decreases significantly during the first year the pavement is in service.
