The role of unsaturated condition and suction in the weathering mechanisms in flysch marls

The weathering of marls from Dalmatia (Croatia) is approached from the aspect of unsaturated conditions and suction through the first findings of a new scientific project dealing with experimental and numerical investigations of mechanisms in unsaturated geomaterials. This is done by connecting the reliable previous own research results obtained on flysch marls (database with approximately 1500 samples) and findings from the research concerning unsaturated materials of similar behavior and composition. The expected suction ranges and soil water characteristic curve (SWCC) shape parameters were determined and described, as well as role of matric suction and SWCC in the engineering behaviour of marl, types of degradation and parameters of significance for further research program. The results of analyzes conducted, data collected, and an overview of experimental and numerical methods suitable for further research were also given.
