Describes the characteristics of the five experimental pavements built between 1976 ~ 1977, amd gives initial conclusions concerning their use. Descril~ions of some of these pavements have already bee~ published. The feasibility of such a structure seems to have been established. The evolution of these pavements under traffic will make it possible to specify the level of traffic beyond which special characteristics of the improved subgrade (drainage course or treated course) will have to be imposed.
