Structure and composition of polymer-bitumen composites

Characterization of asphaltenic material obtained by treating of vacuum residue with different reactive molecules

“…It is found in the literature, that air blowing was industrially used for the modification of soft bitumen for hardening. However, it was later found that air blowing increased fragility of the binders as well as higher aging susceptibility which was not good for paving purposes [1][2][3]. Rheological modification of a bitumen with maleic anhydride and dicarboxylic acids was studied by Herrington et al [4].…”
