FLEXIBLE PAVEMENT ANALYSIS SUBSYSTEM

This paper presents an outline of the analysis techniques proposed for use in a pavement design check procedure that has been developed in the federally coordinated program of highway research on new methodology for flexible pavement design. The concepts and formulations used in the method have been developed in the National Cooperative Highway Research Program and by staffs of the Federal Highway Administration and the state transportation and highway departments. The techniques presented reflect current knowledge, and changes will be made as new information becomes available. The proposed structural analysis subsystem is based on the assumption that portions of the pavement act as viscoelastic elements, others as plastic elements, and others as elastic elements. The method also accommodates the important concept of element responses altered with temperature and loading rate fluctuations. The subsystem is incorporated in a procedure by which it is possible to check existing designs for structural adequacy to resist pavement damage due to cracking, rutting, and roughness. Eventually this subsystem will be integrated with a pavement management system that will allow consideration of optimum design concepts with respect to the planned used and life of the proposed roadway.
