Abstract
The flat dilatometer in situ testing device (DMT) is extremely simple to operate and maintain. The simplicity and low initial cost of the equipment is one of the main advantages of the flat dilatometer as an in-situ testing device. However, the simplicity of the equipment does generate some difficulty with the interpretation of the results. The discussion is concentrated on the soil classification using DMT in the present paper. Based on limited available test data, we investigate the reliability of the test results for classifying the soils from the DMT and propose a new soil classification using the DMT. A larger data base may enable a more definite soil classification to be established.
