FIELD: construction.
SUBSTANCE: invention relates to production of polymer-bitumen binder, containing polymer additives, specifically to composition of polymer-bitumen binder for asphalt concrete pavements, intended for use in road construction, as well as in construction of roofs, waterproofing. Polymer-asphalt binder composition contains the following components, with their ratio in pts. wt: 100 bitumen, 1–20 dichlorocyclopropanated 1,2-polybutadiene - 1–20. Dichlorocyclopropaned 1,2-polybutadiene has degree of functionalisation of 6–60 mol. %.
EFFECT: invention improves physical-mechanical and adhesive properties of bitumen, increases adhesion of bitumen with mineral material and increases service life of the asphalt concrete pavement.
