Abstract. In the article, scientific-research works were carried out on the effect of types of mineral powder on the strength of the asphalt-concrete mixture. By grinding shale rocks, limestone material, and ozokerite material into powder under the same conditions with the help of a centrifugal impact mill, their mutual properties were compared. Experiments were conducted to study the adhesion of mineral powders crushed with the help of a centrifugal impact mill to flint by forming a binder with bitumen. Laboratory tests on the compressive strength and shear resistance of fine-grained hot asphalt concrete mixtures with the addition of these three types of mineral powders were conducted and the results are presented
Keywords: centrifugal impact grinding mill, technological processes, fine-grained hot dense asphalt concrete, shale, limestone, ozokerite, activated mineral powder from shale rocks
