FIELD: construction.
SUBSTANCE: invention relates to road construction mixtures and can be used in making road concrete asphalt materials. Composition of fiber-containing composite material,%: crushed stone 20–60, mineral powder 4–12, reinforcing material 0.07–0.6, organic binder 4–12, sand – the rest, where the organic binder is a composite of two types of oil road viscous bitumen, in% of the total amount of the binder in the mixture: bitumen of one of the following grades: BND 90/130, BND 60/90, BND 40/60 – 85–95 together with bitumen of one of the following grades: BND 200/300, BND 130/200 – 5–15, and reinforcing material is a set of basalt fiber with density of 54–240 tex with a cutting length of 12–18 mm in amount of 5–40 % of total amount of reinforcing material and polyacrylonitrile fiber with density of 0.17–0.77 tex with a cutting length of 6–18 mm in amount of 60–95 % of total amount of reinforcing material.
EFFECT: higher resistance to transport loads and to influence of climatic factors.
