Zusammenfassung:	A process for manufacturing an asphalt composition comprising aggregate, bitumen, sulphur and an anionic surfactant is disclosed. The process uses sulphur pellets wherein from 0.05 wt% to 10 wt% of anionic surfactant, based upon the weight of the sulphur, is coated on the surface of the sulphur pellet. L'invention concerne un procédé de fabrication d'une composition d'asphalte qui comprend des agrégats, du bitume, du soufre et un agent de surface anionique. Le procédé utilise des pastilles de soufre, dont 0,05% à 10% en poids d'agent de surface anionique, sur la base du poids du soufre, est revêtu sur la surface de la pastille de soufre.
