Minerals used for road building, maintenance and repair are reviewed with a greater focus on minerals used for road building: grit, sand, and dolomite. The paper carries on describing asphalt-concrete coatings and mixtures used for the coatings. The asphalt-concrete mixtures with gravel and dolomite chipping are analyzed. According to their stability, plasticity and porosity (Marshall’s) the usage of mixtures for certain construction class is defined. Is givven a recommendation for using this asphalt concrete mixtures. The major conclusions and the bibliography are presented in the end of the paper.
