Abstract:
The invention relates to a package of performance additives for bitumen or bituminous compositions including an acidic adjuvant and a H 2 S scavenger chosen from organic or inorganic copper salts. The invention also relates to the use of said H 2 S scavenger in order to reduce the H 2 S 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 2 S).

Claim (Index 18):
A process for preparation of a bitumen/crosslinked polymer composition comprising employing a sulfur-donating coupling agent and a stage of treatment of a bitumen or a bituminous composition with:\n from 0.05% to 5% by weight of a H 2 S scavenger selected from the group consisting of copper oxides and their mixtures with a copper compound wherein the copper compound is selected from the group consisting of copper hydroxides, copper hydrates, copper hydroxy carbonates, copper carbonates, copper carboxylates, copper nitrates, copper phosphates and their mixtures, and an acidic adjuvant chosen from phosphoric acids, polyphosphoric acids and their mixtures, the percentages being calculated with respect to the total weight of the bitumen/crosslinked polymer composition.
