Predicting Pavement Performance Using Time-Dependent Transfer Functions.

Abstract

A technique was developed to predict the performance of a pavement system subjected to dynamic load inputs. Transfer function theory was extended in connection with a decretized convolution procedure to define a pavement's time-dependent transfer functions. The transfer functions were calculated from data measured during full scale tests in a service environment. Subsequently, a method to predict deflection output responses was developed for use in conjunction with the calculated time-dependent transfer functions. It was concluded that the characteristics of a flexible pavement could be represented by a series of transfer functions obtained from dynamic tests using practically any prime mover. It was also concluded that the transfer functions contained certain isolated descriptors which were related to the aircraft gear configurations, and other descriptors which were only indicative of the pavement's behavior.
