ABSTRACT
Therefore, the primary source of information about rock-fill behaviour was the observation of real rockfill structures. The dam building industry, with his well-established monitoring tradition, gathered most of the currently available field information. Other recent works using rockfill, like high speed railways, produced new interesting data. Anyway, despite the referred limitations imposed by size, laboratory research works allowed gaining much of the understanding, at least in a qualitative way, about the physical and chemical phenomena involved in rockfill mechanics.
