Abstract. During the construction of experimental sections of road surfaces in v. Ust-Kurdyum of the Saratov district of the Saratov region has been established the efficiency of production and application of cold fiber-containing dispersed-reinforced asphalt concrete mixtures with dispersed bitumen.

A method for accelerating the formation of the structure of cold fiber-containing asphalt concrete by heat treatment of its surface is studied.
Dispersed bitumen after drying the water film has good adhesion to concrete, asphalt concrete and other materials. The asphalt concrete formed as a result of curing on the basis of dispersed bitumen is high-strength, chemical-resistant, hydrophobic and environmentally friendly, corresponding to the existing regulatory requirements for asphalt concrete.

For the production of asphalt mixtures, mass-produced equipment is suitable using materials commonly used in hot asphalt concrete: crushed stone, sand, mineral powder and bitumen. Operations on drying and heating of crushed stone and sand are excluded from the technological process.

Asphalt concrete mix does not stick to the surface of rubberized rollers of vibratory rollers, which allows compacting mixtures with a high content of mineral powder at any time. There are fewer cracks on the surface of the compacted layer than when using a smooth-rolling roller.
The technology is recommended for extended use on roads and streets of localities, and highways with low traffic intensity.
