This report describes the behavior of jointed concrete pavement based on field performance and current analysis and design technology. Distress data from a rigid pavement database and existing analysis programs developed at the Center for Transportation Research at The University of Texas at Austin served as the basis for the analytical procedure. Since environmentally induced cracking in jointed concrete pavement is of considerable importance to the performance of the pavement during its service life, we developed an analysis program, termed JRCP-6, that is capable of modeling the mechanisms that lead to cracking. Special attention is given to modeling behavior of the pavement after cracking has occurred.
