FIELD: construction.
SUBSTANCE: invention relates to the field of road construction materials and can be used in the road construction industry to create modern asphalt concrete coatings. Disclosed fiber-containing mixture includes the following components: crushed stone 20–60 %, mineral powder 4–12 %, water 3–12 %, polyacrylonitrile fiber with density of 0.17–0.77 tex and cutting length of 6–18 mm 0.07–0.6 %, organic binder 4–12 %, sand – the rest. Organic binder is a composite of two types of petroleum bitumen road: bitumen of one of the viscous bitumen grades: BND 200/300, BND 130/200, BND 90/130, BND 60/90, BND 40/60 in amount of 85–95 % of total amount of binder in mixture, and bitumen of one of grades of liquid slowly bituminous bitumen: MG 40/70, MG 70/130 in amount of 5–15 % of total amount of binder in mixture.
EFFECT: obtaining a mixture with high shear resistance, water resistance and ultimate strength.
