An asphalt composition having a low VOC content composed of an asphalt material; a volatile methylated siloxane from the group of linear methylated siloxane, cyclic methylated siloxane, branched methylated siloxane and any mixtures thereof and fillers, additives organic VOC solvents conventionally used in such a composition, wherein the composition has a VOC level that allows the composition to be used in venues having restricted low levels of VOC.

The invention relates to a package of performance additives for bitumen or bituminous compositions including an acidic adjuvant and a H.sub.2S scavenger chosen from organic or inorganic copper salts. The invention also relates to the use of said H.sub.2S scavenger in order to reduce the H.sub.2S emissions of bitumen or of a bituminous composition treated with the acidic adjuvant. The invention additionally relates to a process for the preparation of a bituminous composition. The preparation process according to the invention makes it possible to obtain bitumen/crosslinked polymer compositions having better mechanical and dynamic properties in comparison with the bitumen/crosslinked polymer compositions of the prior art, while substantially reducing the releases of hydrogen sulfide (H.sub.2S).
