 abstract={In this paper some basic physical parameters of compact rocks have been described. These parameters arc used for the evaluation of the usefulness of rock materials in construction industry and road-making. Among these parameters the most important are: compressive strength, bending strength, density, frost resistance, absorbability and abrasion resistance. Investigations were made for different types of rock materials as dolomite, diabase and porphyry. Results of the investigations indicate possibilities of the utilisation of certain rocks in the construction industry. Also possible application in road, bridge, railways and waterways construction arc shown. But in case oftunneling or underground mining basic parameters arc not sufficient. Investigations ofparticular rock parameters must be performed with the special emphasise on strength and strain criteria, ifraw materials are supposed to be used in such industries. Measurements of some specific parameters, like post-critical properties (for instance a drop modulus), can be done only in laboratories, equipped in new generation of strain machines with features of the servo control and high stiff parameters.},
