. In this article, the authors have solved the applied problem of uniform distribution of fiber fibers in cold asphalt concrete mix. The principal possibility of uniform distribution of reinforcing elements in the form of short fibers of basalt and polyacrylonitrile fibers in the volume of reinforced asphalt materials based on microdispersed bitumens has been established. The technology of introducing fiber into mixtures-semi-finished asphalt materials based on microdispersed bitumens has been developed. At an asphalt concrete plant, a suspension ("solution") of basalt fiber or fiber from polyacrylonitrile fibers of the required concentration is prepared in a water supply container. The most appropriate way to mix water with fiber in the flow container is bubbling with compressed air using a compressor, which is the standard equipment of an asphalt concrete plant. Any dispersed-reinforced asphalt materials based on microdispersed bitumen can be prepared using a fiber "solution". Bituminous suspension in conditions that exclude water evaporation (in sealed containers), as a result of spontaneous processes, tends to a stable aggregate state. The most stable aggregate state of the bituminous suspension is plastic. In the process of preparing a bituminous suspension, it is necessary to ensure that it is obtained in a plastic state (similar to plasticine). In the plastic state, the mixture will not delaminate not only during storage, but also during transportation.
