FIELD: manufacture of road-building materials.
SUBSTANCE: method is characterized by addition of wood fibers to mix, said fibers being obtained from wood crumb by drying it in ascending air flow at 120°C followed by breaking-down on mill with cribble-like blades. Prior to be charged into mixer, wood fibers are forced through dies with the aid of ventilator and, for their mixing, a mineral powder, bitumen, and a surfactant are first added into mixer, then stirred, and, in the course of stirring, wood fibers in common with broken stone and sand are charged into mixer.
EFFECT: reduced expenses on powder of mixes and improved their performance characteristics: compression strength and water resistance.
