A process for manufacturing asphalt is disclosed. The process comprises the steps of: (i) heating bitumen; (ii) heating aggregate; and (iii) mixing the hot bitumen with the hot aggregate in a mixing unit to form asphalt. From 10 to 200 wt% of sulphur, based upon the weight of the bitumen, is added in at least one of the steps (i), (ii) or(iii) and from 0.1 to 20 wt% of a compound of formula A, based upon the weight of the bitumen, is added in at least one of the steps (i), (ii) or (iii). Rand Rare independently chosen from C-Calkyl or alkenyl. |
