Carbon emissions analysis of producing modified asphalt with natural asphalt

Abstract The modification mechanism of modified asphalt with natural was analyzed through Fourier transform infrared spectrum. results show that the both and petroleum is mainly a physical blending process. polar functional groups contained in make have characteristic good scaling resistance water stability. Subsequently, carbon emissions each link production stage were quantified, influence mining, transportation, processing on total all by establishing emission calculation model production. GREET showed equivalent dioxide (CO 2 e) rock mining only 9.4% crude oil At same time, CO e 44.7% lower than asphalt, transportation accounted for 1/3 transportation. Furthermore, increased energy consumption caused will partially offset contribution to reducing emissions. Meanwhile, when content exceeded 18%. Thereafter, analytic hierarchy process had largest weight asphalt. Ultimately, it significant further reduce increasing which then inevitably lead reduction
