FIELD: construction.
SUBSTANCE: bitumen modifier includes oil road bitumen, rubber crumb, secondary polyethylene, as a structuring additive it includes a nanodispersed component - hydrate lime, and as a surfactant - adhesive "Azol-1003" at the following ratio of components, wt %: bitumen BND 60/90 - 30-42, rubber crumb - 16-21, secondary polyethylene - 37-41, hydrate lime - 4.0-6.0, adhesive additive - 1.0-2.0.
EFFECT: development of an effective complex bitumen modifier for asphalt concrete, making it possible to improve operational characteristics of a bitumen binder for asphalt concrete mixtures, improving their shift, crack, corrosion resistance, increasing service life of coatings.
