A mechanistic-empirical approach is implemented here to simulate the deterioration of a pavement. A quarter car model is used to simulate pavement/vehicle dynamic interaction and a feedback mechanism is implemented after each run to update the pavement profile after the passage of each axle. In this way, the influence of Statistical Spatial Repeatability (SSR) is incorporated into the pavement damage model. The model is run for two sample profiles. The first is a simple step profile which demonstrates that the patterns of damage relate to the two natural frequencies of the quarter car. An initially random profile is also investigated. A complete history of the surface profile during its life demonstrates how the peaks and troughs migrate in response to the evolving pattern of SSR.||Type of material:||Conference Publication||Publisher:||Research Publishing Services||Copyright (published version):||2010 Research Publishing Services||Keywords:||Pavement; Statistical mechanics; Stochastic processes; Permanent deformation; Spatial repeatability; Dynamics; Mechanistic-empirical||Language:||en||Status of Item:||Peer reviewed||Is part of:||Deodatis, G. and Spanos, P.D. editors, Computational Stochastic Mechanics, Proceedings of the 6th International Conference (CSM-6), Rhodos, Greece, June 13-16, 2010||Conference Details:||6th International Conference on Computational Stochastic Mechanics (CSM-6), Rhodos, Greece, June 13-16, 2010|
