Analyzing Applicability of Existing Classification for Hard Carbonate Rock in Mediterranean Area

Based on many years of research focusing on a number of significant structures (bridges, tunnels, dams, high rock slopes, etc.) designed and realized in the Adriatic coastal area, we have collected a large quantity of engineering-geological and geotechnical information. To devise engineering geological (IGM) and geotechnical models (GM), it is indispensable to conduct engineering rock-mass classification using one of the widely recognized methods. Starting from the existing RMR and Q classifications, we have developed a new "n" classification which enables a more complete limestone classification and categorization, using a relatively simple procedure.
