Detail FLAT DILATOMETER ( DMT)
DMT determines in a quick, precise, simple and economicalway various important parameters used in geotechnical design. The results are highly repeatable and independent from the operator. The blade is advanced in the soil by pushing the rods with penetrometers or drill rigs, or a variety of field machines. In this way boreholesand sample disturbance areavoided.
The measurements are carried out directly on the in situ soil. The results are immediately available in a report format, containing graphs and tabular outputs. The DMT is used in 50 countries. It is standardized in the ASTM( USA) norms and in the Eurocode. The equipment and test procedure are described in detail in the Report ISSMGE Committee TC16 ( 2001) , downloadable from the website.
