The invention provides a sulphur pellet comprising at least one H2S-suppressant. The invention further provides a process for the manufacture of sulphur pellets comprising at least one H2S-suppressant, comprising the steps of: (a) mixing elemental sulphur, one or more H2S suppressants and optionally a filler in a mixing unit to obtain a mixture; (b) shaping and/or pelletising the mixture obtained in step (a) in a pelletising unit to obtain H2S-suppressantcomprising sulphur pellets. The invention further provides a process for the manufacture of a sulphur-comprising asphalt paving mixture comprising the steps of: (i) preheating bitumen at a temperature of between 140 and 180 <°>C; (ii)preheating aggregate at a temperature of between 140 and 180 <°>C; (iii) mixing the hot bitumen with the hot aggregate in a mixing unit, wherein sulphur pellets comprising H2S-suppressant according to the invention are added in at least one of the steps (i), (ii) or (iii). The invention also provides the use of a sulphurcomprising asphalt paving mixture comprising H2S suppressant in the paving of roads. |
