Analizing 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 rocks slopes, etc.)designed and realized in the adriatic coastal area, we have collected a large quantity of engineering-geological and geotechnical information. To device 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.
