applied geology laboratory

The Applied Geology Laboratory of our department is equipped with modern test equipment in accordance with today's technology. Almost all of the test equipment used to determine the physical and mechanical properties of soils and rocks are available in our laboratory. Our laboratory consists of sections where rock mechanics and soil mechanics experiments are carried out, sample preparation section where coring, cutting and trimming processes are carried out for test samples to be used in rock mechanics experiments and aggregate experiments. In these laboratories, experiments are carried out according to the most widely used recommended methods and standards in the world such as International Society of Rock Mechanics (ISRM), American Society for Testing and Materials (ASTM) and British Standards (BS) and Turkish Standards (TS) of the Turkish Standards Institute (TSE).
