In modern science and practice, the main principle of interaction between bitumen and mineral material grains is that the bitumen film covers the grain of the mineral material. The presented work opens a cycle of studies of the reverse nature of this interaction – when a micro-dispersed drop of bitumen is covered with a powdered layer of a mineral material (nano- or micro-powder). In fact we are talking about the production of nano-material in the form of a bituminous suspension on direct solid emulsifiers and materials based on it. This article presents the results of road repair in the village of Ust-Kurdyum, Saratov Region, with the use of fiber-containing asphalt concrete mixes with dispersed binder. The technology is recommended for extended use for roads and streets of settlements, and for highways with low traffic intensity. The achieved technical result is the prevention of segregation (stratification) and caking of asphalt concrete or bituminous-mineral composition during its storage and transportation, and increasing the adhesion of the binder to the mineral materials of asphalt concrete or bituminous-mineral composition, when using it, due to ensuring the plastic properties of the bituminous binder and road material as a whole.
