Web15 nov. 2024 · It has been shown that bitumen differs in terms of wax. After fractionation, more wax is found in the maltenes compared to the bitumen, and this is even more evident when bitumen is aged. For one bitumen, asphaltenes from the virgin binder do not contain carbonyls, which all fall into the maltenes. WebThe naphthene aromatics and polar aromatics improve the solvent's ability to disperse asphaltenes. Thus, the more of the saturate and asphaltene fractions in an asphalt compared with the other two fractions, the less compatible, or gel-like, the asphalt will be. Webtene and maltene components of the PMACs. The molar mass distributions as obtained by peak position calibra-tion using polystyrene standards results in very distinctive molar mass ranges for each of the PMAC components, i.e., polymer molecule, asphaltenes and maltenes.
