Many papers have been published outlining the principles of analytically based structural design methods for flexible pavements. This paper concentrates on the actual calculations and presents a detailed design method which results from rational simplification of the problem. It applies to pavements with bituminous bound bases. Hitherto, the use of digital computers in theoretically based design has been something of a barrier as far as the practising engineer is concerned. This has now been overcome by presenting all the information in the form of charts, graphs and relatively simple equations. The object of putting this design method forward is to offer to engineers a simple procedure which, in use, requires that the important variables in the problem are properly considered. Empirical methods and previously presented theoretically based design charts do not allow the user to appreciate what he is actually doing. The aim is, therefore, partly educational since the method has yet to be fully validated in practice though, under commonly occurring conditions, it produces designs similar to those arrived at by the use of present practice. If advances in pavement design are to be achieved, greater appreciation of the basic principles is required by a greater number of highway engineers and this paper is intended as contribution towards that end. /author/
