Pressuremeter testing activities are of great interest for scientists and engineers concerned with the mechanical behaviour of civil engineering materials. The proceedings include the first Menard Lecture presented by Professor Branko Ladanyi and 57 technical papers from 16 countries. They are related to the application of pressuremeter testing to granular and alluvial soils, clay, rock, concrete and permafrost, and geotechnical design. It also includes a session on technological developments in the design, fabrication and installation of pressuremeters.
