The article reviews the development of (1) Empirical Flexible Pavement Design Methods: CBR, Plate Bearing Test, Triaxial Test and Soil Classification Methods, and Empirical Road Test Studies, (2) Theoretical Design Methods: Soil Mechanics Methods and Techniques using the Layered Elastic Theory, and (3) Deflection Methods based on the concept of the latter criterion is being used more in the design of bituminous concrete overlays than in the design of new pavements. The various steps in flexible pavement design are outlined: assessment of design traffic and subgrade quality, evaluation of layer thicknesses in terms of pavement flexibility, and use of a servicebility index to determine the environmental causes of pavement deterioration. This paper was presented at the annual Engineering Conference of The Institution of Engineers, Australia, held in Canberra, April 1972.
