Methods of uniform distribution of fibrous materials in asphalt materials with dispersed bitumen were studied. The key issue in this area is the technology of introducing reinforcing elements into the volume of asphalt concrete mix. Fiber from polyacrylonitrile fibers is considered as a reinforcing material. To achieve the maximum reinforcing effect for any materials, including asphalt, due to the introduction of short fibers and threads, their uniform distribution in semi-finished mixtures and in the formed structural material is necessary. The principal possibility of uniform distribution of reinforcing elements (in the form of short fibers of polyacrylonitrile fiber) in the volume of reinforced asphalt materials based on viscous dispersed bitumens is established. A method for the uniform introduction of fiber into the bitumen suspension for the arranging springing asphalt concrete layers has been developed. For the first time, a material from a bituminous suspension reinforced with polyacrylonitrile fiber, which is not destroyed in thin layers under the action of bending loads, but reversibly deformed, was obtained.
