Abstract: This article discusses the theoretical issues of the formation of the structure of adsorption-solvation layers of asphalt-chrysotile binder on the surface of mineral materials of road asphalt concrete. Interaction of dispersed fibrils of chrysotile reinforcement with mineral components of asphalt concrete mixture in the adsorption layer is considered. It has been established that the diameter of dispersed reinforcement plays a key role in the formation of homogeneous and durable adsorption-solvation layers of organic binder in reinforced asphalt concrete. It is shown how the interaction between the particles of the mineral part and the formation of bonds between the near and far series of contacts is carried out. The influence of the content of one percent of chrysotile asbestos in asphalt concrete on such indicators as: shear strength, tensile strength in bending at negative temperatures, fatigue life, corrosion resistance is analyzed.

Keywords: asphalt-chrysotile binder, asphalt concrete, chrysotile-asbestos, dispersed fibers, adsorption layer, mineral material.
