Conference. PROC.6TH CONF.AUSTRALIAN ROAD RESEARCH BOARD, V6, PART 4,1972# P843-886 • C%u~rent design and analysis methods for multi-layer pav~nents see based on c~rtain critical stresses, strains and displacements which should not exceed specified limits if pavement failure is to be avoided. For exsmple, maxlmt~n vertical strain has been used as a criterion of sub~ade behaviour, and m a x i ~ n tensile strain as a criterion of the behaviour of surface layers composed of bittmdmous mixes. In this paper the elastic theory is used to predict the magnitude of these critical stresses, strains and dlsplac~nents and the results sre preserved in a ~raphical fc~m that allows rapid assesm~ent of the ~ffects of the variables involved. In addition the plots presented provide a convenient method of pav~nen~ design and analysis based on a s s t ~ criteria of pavement perfc~mance.
