The paper solves the task of obtaining the technological conversion - three-component system ‘microdispersed mineral grain - microdispersed particle of viscous bitumen - water’ at consecutive dosing of raw material components at the asphalt-concrete plant. It is necessary to prepare the bitumen suspension of viscous consistency to avoid delamination of bitumen slurry, to ensure its transportation by dump trucks, storage in the excavation and loading. The authors propose to refuse to heat bitumen in winter and to use ready-made materials for road construction in cold form. The addition of mineral components will make it possible to produce cold analogues of long-term storage asphalt concrete mixtures at Russian enterprises.
