FIELD: manufacture of road building materials; reinforcement of asphalt pavements; construction of automobile roads, aerodromes.
SUBSTANCE: proposed method consists in introduction of cellulose-containing material prepared beforehand into asphalt-and-concrete mix; used as cellulose-containing material is linen straw. Preliminary preparation of linen straw is continued till semi-cellulose has been obtained, after which it is mixed with bitumen at ratio of semi-cellulose to bitumen of (1-3): (1-2). Then, mixture is granulated and is introduced into preheated asphalt-and-concrete mix in the course of mixing its components.
EFFECT: improved qualities of mix; wide range of raw material sources.
