PROPOSAL FOR METHODOLOGY TO BE APPLIED TO ROAD CONSTRUCTION IN THE KARSTIFIED CARBONATE AND CLASTIC (FLYSCH) TERRAINS IN SOUTHERN CROATIA

Abstract

The suggested methodology includes an approach to investigations which has the objective of obtaining all relevant data on the environment through which the road corridor is planned. This implies an integrated approach to the programming and the implementation of investigation works which, however, cannot be applied to all cases. Frequent changes which ure encountered over small distances in the karst and flysch terrains can be studied simultaneously since these layers are generally in contact in the coastal regions in Croatia. The paper presents an efficient methodofogy applied to investigation works planned according to types of structures and phases of the road planning. The preliminary design phase should include all planned investigation works in order to solve thc number of problems relevant to the final design phase and to the conditions and possibilities of road construction. The paper also stresses the necessity of precisely defining the lithostlratigraphical and tectonic features as a prerequisite for planning the scope and quantity of investigation works and for proper interpretation of all engineering-geological and hydrogeological relations.
