FIELD: chemistry.
SUBSTANCE: invention relates to the field of chemistry and petrochemical production and can be used in the construction, reconstruction and repair of roads, bridges and airfields as a polymer-bitumen binder. The polymer-bitumen binder includes bitumen in its composition and additionally contains a polymer modifier, including ethylene propylene rubber and polyethylene, taken in a mass ratio of 0.7 to 0.3, respectively, while bitumen is contained in an amount of 95 and polymer modifier 5, wt. %.
EFFECT: increase in strength properties, such as extensibility, softening temperature, elasticity and uniformity.
