A new rock classification named as Rock Mass Quality Rating (RMQR) proposed by the authors (Aydan et al. 2013). This new rock classification quantify the state of rock mass and possible geo-mechanical properties of rock masses can be estimated using the classification system together with intrinsic geo-mechanical properties of intact rock. This system eliminates some shortcoming of previous systems. It is correlated with existing quantitative rock classification systems as well as qualitative rock classification systems used in Japan. The fundamental parameters of this system are explained and the correlations with quantitative and qualitative systems are presented. Further applications of this new system are pointed out.
