The Kansas Department of Transportation (DOT) uses the 1993 DARWin version of the 1986 AASHTO Guide to design flexible pavements and rehabilitation strategies of flexible pavements. One of the inputs needed for the flexible pavement design procedure is the structural layer coefficient for each pavement layer. The Kansas DOT procedure to assign structural layer coefficients was developed years ago and based on an analysis of flexible pavement performance data and layer properties. It has been recently suggested that the Kansas DOT increase the structural layer coefficients because of changes in material and construction specifications. Different procedures can be used to estimate the structural layer coefficients for flexible pavement design. As part of the study entitled Determination of the Appropriate Use of Pavement Surface History in the KDOT Life-Cycle Cost Analysis Process an evaluation of the procedure that Kansas DOT uses to assign structural layer coefficients to different pavement materials was completed. This report provides the results of that evaluation.

This synthesis will be of interest to pavement, highway, and geotechnical engineers, and others interested in pavement structural design practices. Information is provided on flexible and rigid pavement design, design elements common to flexible and rigid pavement, and flexible and rigid pavement overlay design. Additionally, the synthesis discusses pavement research currently underway and recently completed by researchers of the United States and Canada. The structural design of flexible and rigid pavements has evolved from the application of engineering judgement to include a variety of processes. This report of the Transportation Research Board describes the various methods for structural pavement design in the United States and several Canadian provinces. Only the structural aspects of design are considered, that is, those intended to provide strength or stiffness to the pavement. The functional aspects of design (such as skid resistance), are not considered.
