Abstract : The response of the rigid pavement slab-joint-base structural system is complex, and accurately predicting the response of such a system requires a significant degree of analytical sophistication. The research reported in this dissertation has defined some essential features required to adequately model the system and has demonstrated a technique to develop a comprehensive three-dimensional (3D) finite element model of the rigid pavement slab-joint-foundation structural system. Analysis of experimental data from the 1950's confirms that explicit modeling of dowels is not required to model the structural response of the system. Additional experimental data gathered as a part of this research indicates that joint response depends upon the presence and condition of a stabilized base. The presence of cracking in the base and the degree of bonding between the slabs and stabilized base course influences the structural capacity and load transfer capability of the rigid pavement structure. The finite element models developed in this research indicate that a comprehensive 3D finite element modeling technique provides a rational approach to modeling the structural response of the jointed rigid airport pavement system.
