Chemical aging of BND 40/60 bitumen in the presence of an oxidation inhibitor under the conditions of heating in a thin film at 163°C for 5, 10, 15, and 20 h was studied. An increase in the asphaltene content, associated with the new formation of a colloid-unstable high-molecular-weight fraction A1 of increased aromaticity, was observed to a lesser extent than in the straight bitumen.
