FIELD: chemistry.
SUBSTANCE: binder is a mixture of a polymer-bitumen binder, of structure-former, and mineral components in the following ratio of components, wt %: polymer-bitumen binder - 65-75, structure-former 15-25, mineral components - 10. When this polymer-bitumen binder consists of bitumen, plasticiser, polymer SBS, crushed rubber and reagent of increasing the uniformity and activity of the polymer-bitumen binder in the following ratio of components, wt %: plasticiser - 5, polymer SBS - 1.5-2, shredded rubber - 20-25, reagent of increasing the uniformity and activity of the polymer-bitumen binder - 1-2, bitumen - the rest.
EFFECT: producing a polymer-bitumen binder with high physical and mechanical characteristics.
