	Summary:
	As a part of geotechnical research at several locations in Republika Srpska and Federation of Bosnia and Herzegovina, detailed geotechnical investigations of rock masses were carried out. On the abovementioned exploration sites, terrain is composed of different rock masses (Cretaceous limestone, Palaeozoic gneiss, Mesozoic peridotite and serpentinite). This paper presents an overview of correlation between uniaxial strength, elastic wave velocity and rock mass quality, on one side and in situ obtained results of rock mass deformability, on the other side. Modification of the correlation between deformation modulus and rock mass quality in a form of correctives for each of the equations by Galera, Alvarez and Bieniawski, was also presented. All deformability tests were carried out by the Institute for the Development of Water Resources „Jaroslav Černi” Belgrade.
