Sažetak
The Eocene flysch in the region of Split (Dalmatia, Croatia) is characterized by the presence of layers with different characteristics. It includes thin-layered marls, clayey marls, calcareous marls, clastic layered limestones, calcarenites and breccias. Those parts of the terrain which can be described as soft rocks according to mechanical means, exposed to the weathering processes and degrading forces reduce the durability within the "engineering time scale". However, it is now possible to protect the flysch material from the erosion processes caused by weathering during the design and construction phases. Unfortunately, there are no appropriate methods for reaching conclusions as to which parts of the flysch structure should be protected. The wetting-drying process is considered to be the most important process during weathering. According to the analysis, as the most appropriate due to the mentioned characteristics, the tests are chosen as index properties. Some of these tests are modified in order to adapt them to the determined characteristics of some flysch layers. All these modifications and the new proposed tests are explained in the paper. The correlations between the measured values are used as the basis for the classification of the analyzed soft rock according to its resistance to weathering processes. The classification includes three main groups.
