FIELD: chemistry.
SUBSTANCE: concentrated binding substance contains at least 50 wt % a soft aromatic petroleum base, at least one polymer and optionally an asphalt base. The soft aromatic petroleum base contains one or more aromatic petroleum fractions taken separately or in form of mixtures, where said aromatic petroleum fractions are obtained during dearomatisation of petroleum fractions obtained when refining crude oil. The polymer contains one or more copolymers based on links of conjugated diene and an aromatic monovinyl hydrocarbon and content of its binding substance is greater than or equal to 20 wt %. The invention also relates to a method of producing a concentrated binding substance and use thereof to produce diluted asphalt-polymer binding substance which is used in various areas of road construction, as well as for industrial use.
EFFECT: binding substance has slowed gelling, is stable during storage and has low viscosity, which allows for its pumping using ordinary pumping systems.
