This paper summarizes critically the present state of the art of analytical flexible pavement design. Its scope is limited to fully flexible construction and to those procedures with the potential for implementation in the UK. Pavement models that can be used to evaluate the response of the system to external loads are considered initially before a discussion of the inputs necessary to use these models including an assessment of available procedures to predict both traffic loading and material properties. Finally, established performance criteria are reviewed and further requirements for the full implementation of the analytical method are described. It is argued that the current development of the analytical method allows a significant understanding of pavement behaviour to be developed and that it should therefore be introduced as an integral part of the design procedure undertaken in parallel with traditional methods. It is argued also that the analytical method provides an inherently improved procedure compared with existing empirical methods for extrapolating known pavement performance relations to higher cumulative traffic levels. However, until such time as improved performance prediction models are included as an integral part of the analytical method, its ability to recommend authoritatively the use of radically new materials will be severely limited.
