The effect of different parameters on CIR yield has been studied. The procedure for obtaining CIR which may be used as bitumen modifiers has been proposed. The resins were synthesized via ionic and radical copolymerization of unsaturated compounds presented in LFCT. It was established that CIR obtained via ionic copolymerization had not functional groups. In the case of radical copolymerization with addition of oxygen-containing functional monomers the resins with free carboxy or epoxy groups were synthesized. When adding CIR obtained via ionic copolymerization to the road bitumen BND 60/90, its softening temperature and adhesion were found to be increased.5481 Product Description popup.authors Івашків Остап Петрович Астахова Олена Тарасівна Братичак Михайло Миколайвич Гаргай Христина Іванівна popup.nrat_date 2020-04-02 Close
