The results of an investigation of 8 highway sections in Switzerland opened to traffic in 1966 to '75 are presented. Their asphalt concrete pavements placed on unbound materials showed considerable difference in behaviour under the influence of heavy traffic and relatively severe climatic conditions on the Swiss Central Plateau. The goal was to determine the permanent deformations of each pavement course, mechanical properties and other characteristics in situ and in the laboratory (in vitro). The long-term pavement performance was evaluated in 1990. Findings from this research have already been taken into account in the design of new asphalt concrete pavements which prove effective under almost all traffic loads and climatic conditions.
