Processes involved in the approach to pavement design described in this paper are directed primarily towards providing structural adequacy of "flexible" highway pavements. Little attention is given to the task of pavement-type selection (from the two generic pavement types commonly used--rigid and flexible). No attention is directed towards an even more basic point in the decision-making process, the determination of whether a highway should be built or whether funds should be used for other public services. This paper is devoted principally to a description of a model whereby the structural adequacy of a pavement can be assured. No attempt is made herein to describe in detail problems of pavement design as it relates to functional adequacy of the pavement system to perform its intended purposes. Some aspects of functional performance, however, which are closely related to the pavement design schema used in Kentucky will be mentioned briefly at various points in the discussion. Pavement design has often been approached from two general but differing points of view. The practicing engineer on the firing line often approaches the task from the standpoint of pavement performance. Educators and researchers, on the other hand, often approach the problem on the basis of theoretical concepts. The structural design model presented herein is hopefully an appropriate merger of the two approaches, providing a basic and fundamental theory, applicable to many situations, to which has been wedded the many years of experience with highway pavement performance in the Commonwealth of Kentucky. /Author/
