The subject of this lecture is the development of analytically based asphalt pavement design and rehabilitation during the 30-year period from 1962 to date. The perspective presented herein has been influenced strongly by research at the University of California at Berkeley during this period, research performed by many who have contributed significantly to the field. Moreover, the interrelation of asphalt pavement design and rehabilitation and asphalt-aggregate mix design is emphasised; they must be considered together to develop optimally performing pavement structures, whether new or rehabilitated.A brief summary is given of available analysis procedures that have been developed during this period, analysis procedures made possible by the advent of the electronic computer. Included are references to available multilayer elastic and viscoelastic analyses using closed-form solutions and finite-element idealisations. Although the majority of these solutions are based on so-called static load response, a recently developed computer solution permits treating the load and pavement response dynamically.
