ABSTRACT
This paper wants to provide to professionals in the design and execution of roads, experimental data about geomechanical and technological characteristics of the rocks, which can be used for improving foundation soil in the Rovinari mining basin. In the study were determined the following geomechanical features: freeze-thaw resistance, uniaxial compressive breaking strength, wearing resistance using Los Angeles method, wearing resistance using Deval method, abrasive resistance using Baron method, resistance coefficient (Protodiakonov) and alkali-aggregate reaction. These properties were studied in interaction with the foundation soil. These trials were carried out on samples collected from 8 points located on the river Jiu, of which 5 of them were gravel pits and 3 were quarries. The results were presented as average values, but we also presented the maximum and minimum values for each sort and collecting point.
