Zusammenfassung:Introduction. Increasing the load on highways and constantly increasing the intensity of traffic requires the use of road construction materials with improved physical and mechanical properties. Asphalt concrete is one of the most common and effective materials, which allows to provide the necessary strength and durability of the pavement structure. However, the use of traditional materials for its preparation - mineral material and road bitumen has a limited resource, which does not always meet traffic conditions. Modern scientific research in materials science allows to use mixtures of asphalt concrete and asphalt concrete road with the use of basalt fiber.Apply mixtures of asphalt concrete and asphalt concrete road with the use of basalt fiber, allows to increase the mechanical characteristics - tensile strength and resistance to fatigue from repeated loads, which increases the crack resistance of asphalt concrete layers of pavement structures, as well as increases resistance to shape change. accumulation of residual deformations.Problem Statement. From the literature analysis it is established that the coating of non-rigid pavement is in difficult operating conditions, which is confirmed by the intensive growth of defects in the form of tracks, landslides, inflows, cracks, due to increasing parameters of transport loads and high summer temperatures, so there is a need new materials.Purpose. Is to study the impact of the effectiveness of asphalt concrete reinforced with basalt fiber.Results. The results of physical and mechanical properties of asphalt concretes with the use of basalt fiber are obtained. The results of formation of residual deformations in the form of track in asphalt concrete with the use of basalt fiber are obtained. As a result of the conducted researches the analysis of efficiency of application of basalt fiber in asphalt concrete mix is executed.On the basis of the carried-out researches the basic requirements to asphalt concrete mix with use of basalt fiber are establishedConclusions. The research results were used in the development of regulations for the design, construction and repair of asphalt layers of roads in Ukraine.Keywords: asphalt concrete road with basalt fiber, asphalt concrete mixes with basalt fiber, loading, covering, stability, temperature.
