Manufacture of asphalts of different brands by compounding vacuum residue with natural asphaltite
The reasons for the time changes of asphalt properties (aging) are considered as a factor of the formation of the asphaltene solid phase. The possibility of the replacement of oxidized asphalt having an unstable structure with a vacuum residue compound with natural asphaltite possessing the stable solid-phase structure was studied.
