Marly soft rocks from Dalmatia (Croatia) and Budapest (Hungary) – correlation of intact rock physical and mechanical properties

Soft rocks have an important role in the geological structure of Dalmatia (Croatia) and Budapest area (Hungary). In general, soft rocks are transitional material between the hard rock and soft soil with compressive strength below 25 MPa. A lower limit of soft rock strength is a subject of many discussions in geotechnics. Most of the soft rock material that occurs in the above-mentioned regions can be classified as marly material, which varies from clayey marls and marly clays to calcareous marls. These materials can cause serious problems in design and construction, due to their complex behavior under atmospheric conditions. Their properties mostly depend on their clay and carbonate contents. For the purpose of better understanding soft rocks behavior and their properties, a database with samples collected throughout Dalmatia was made and compared with the Budapest area samples. Based on the data from the database, correlations between physical and mechanical properties of intact marly rock were obtained. The relationships were applied to the Budapest area samples in order to validate the correlations and their applicability to materials from different regions and different geological origin.
