Predicting airfield deflection responses using transfer functions
Abstract
A methodology is developed to utilize transfer function theory to predict pavement deflection responses due to 727 aircraft loadings (signatures). There is a linear relation between the pavement's transfer function in the time-domain and the frequency domain. That is, a linear relationship exists between the transformed pavement response function and the transformed aircraft signature. Use of the Falling Weight Deflectometer (FWD) testing device provides a fast and non-destructive means of determining a pavement's transfer function. Given the transfer function at two locations and the aircraft signature at one of these, predictions can be made of the pavement's response to that aircraft at the second site. Basic data for this study was provided by the Waterways Experiment Station, Vicksburg, Mississippi. There is reason to believe that these data are not correct. Hence users of the developed procedure should be cautioned that the method, which predicted good approximations of measured airfield pavement responses, has not been tested using reliable data.
