Abstract

AbstractThe article is devoted to the study of the physical and mechanical properties of asphalt concrete mixtures with the addition of asphaltite into the binder and into the asphalt mixing plant. The process of prepar ing materials for research has been described, the selection and design of the composition of the asphalt concrete mixture has been made. A step- by-step technology for the production of an asphalt concrete mixture with artificial asphaltite has been presented. Results of the experiment have shown a significant increase in the physical, mechanical and operational properties of asphalt concrete pavements modified with artificial asphaltite of the asphalt concrete mixture. It leads to the increase in the service life of roads. On the basis of the experiment and analysis the optimal formulation of the asphalt concrete mixture using artificial asphaltite has been proposed and the optimal method of introducing the additive at the asphalt concrete plant has been determined.KeywordsRoad pavementArtificial asphaltiteAsphalt concreteOil bitumenModificationBituminous astringent
