Abstract.<\/strong> This article presents the results of a comprehensive study aimed at substantiating the feasibility of using rocks containing chrysotile asbestos (using the Alapaevsk chromite massif, Ural region, as an example) as an alternative mineral raw material for the production of asphalt concrete mixtures. It is demonstrated that the rock produced at the III Dayennyi Rudnik quarry, which contains chrysotile asbestos fibers, meets the physical and technical properties requirements for asphalt concrete mixture mineral components.<\/p>\n

To optimize the composition of the asphalt concrete mixture, the authors used a full factorial experiment with varying fiber content (0,5\u20132,5 %) and bitumen (5,5\u20137,5 %). Regression models and three-dimensional response surfaces were constructed. The optimal chrysotile asbestos fiber content was determined to be 1,2\u20131,8 % and bitumen content was 5,9\u20137,2 % (over 100 % mineral content).<\/p>\n

The asphalt concrete composition obtained by the authors is characterized by improved performance properties: compressive strength at 50\u00b0C increases by 30\u201340 % compared to compositions without reinforcement, the water resistance coefficient reaches 0,95\u20131,00, and crack resistance at 0\u00b0C remains within acceptable limits. It was shown that the high specific surface area (10\u201325 m\u00b2\/g) and adsorption activity of chrysotile asbestos fibers allow for the complete elimination of commercial mineral powder from the asphalt concrete mixture, thereby reducing the economic and transportation costs of its production. The use of overburden and waste from chrysotile-containing deposits helps reduce the anthropogenic impact and expand the raw material base for road construction in regions experiencing a shortage of traditional aggregates. The proposed approach enables the design of asphalt concrete mixtures with predictable characteristics while simultaneously conserving resources and reducing the cost of asphalt concrete pavement construction.<\/p>\n
