Abstract
AbstractIn addition to laboratory analysis, tests can be carried out on site to support the geological underground documentation. They should cover the important parameters on the project and be easy and time‐saving to implement. This article describes a selection of methods and their suitability for use on construction sites. The tests comprise determination of water content, grain size distribution as well as the implementation of point load and Cerchar abrasiveness tests. For all these tests, the practical application on the site of the Koralm Tunnel contract KAT 3 and implementation details are explained. For all on‐site tests, it is recommended that the results gained should be compared with the experimental procedure and the results of laboratory analyses.
