摘要

•Acidic, basic and neutral fractions of maltenes and asphaltenes were evaluated.•Up to 56% of Ni and 53% of V were lost after asphalt long-term aging.•V losses were attributed to emission of volatile compounds after thermal aging.•Ni losses were attributed to both UV–VIS radiation and sample heating.•Both metals were found in air particulate matter from asphalt mixing plants.
