Abstract: An approach using a new modeling technique (transfer function theory) was developed to predict the performance of a pavement system subjected to dynamic load inputs. Transfer function theory was extended in connection with a convolution procedure to define a pavement's time-dependent functions. The time-dependent transfer functions were calculated from data measured during full-scale tests in a service environment. Deflection output responses were calculated from the time-dependent service environment. The study indicated that the characteristics of flexible pavement could be represented by a series of time-dependent transfer functions obtained from dynamic tests using practically any prime mover. The time-dependent transfer functions contained some descriptors which could be related to the aircraft gear configurations, and other descriptors which were indicative of the pavement itself.
