Sedimentology in the service of engineering geology: Study of some results of the explorations for highway construction and tunneling in Croatia

Exploration for highway construction and tunneling in Croatia besides normal field investigations, involved sedimentological survey. This paper presents results of laboratory and field investigations which can improve our conclusions about rock mass quality. The authors encourage the application of sedimentology in engineering geology, particularly in karstic regions, for more appropriate understanding of the rock mass and intact rock. Introduction of sedimentological modelling into this project indicates a great influence of sedimentology into engineering geology and it certainly enhanced our engineering-geological model.
