FIELD: chemistry.
SUBSTANCE: invention relates to construction material industry, to production of modifying agent for polymer asphalts used in road construction and civil engineering for road making, road bed joint sealing, aerodromes, sports grounds; roofing and waterproofing of building structures and bridgework; in paint-and-varnish industry. The invention is a polymeric asphalt modifier characterised in that this material consists of polymeric petroleum resin as polymer and ethylene-vinyl acetate copolymer as solvent and vegetable oil as added plasticiser, ratio of components in wt % being as follows: polymeric petroleum resin 20-80, ethylene-vinyl acetate copolymer 10-30, vegetable oil 10-50.
EFFECT: production of polymer asphalts with improved heat resistance and elastic-strain properties.
