Bituminous composition comprising a bituminous component and a block copolymer composition which comprises at least one of the group consisting of linear triblock copolymers, multi-armed block copolymers and diblock copolymers, which block copolymers comprise at least one block of a monovinylaromatic hydrocarbon (A) and at least one block of a conjugated diene (B), wherein the block copolymer composition which is present in an amount in the range of from 1 to 10 % wt., based on total bituminous composition, has a vinyl content of at least 25 % by weight, based on the total diene content, and any diblock copolymner (AB) present has an apparent molecular weigth in the range of from 60,000 to 100,000.

Composition bitumineuse comprenant un composant bitumineux et une composition de copolymères blocs comportant au moins un élément du groupe composé de copolymères linéaires à trois blocs, de copolymères à deux blocs, lesdits copolymères blocs comprenant au moins un bloc d'un hydrocarbure monovinylaromatique (A) et au moins un bloc d'un diène conjugué (B). Cette composition de copolymère en bloc, présente à raison de 1 et 10 % du poids total, par rapport à la compostion bitumineuse entière, contient au moins 25 % en poids de vinyle, par rapport à la teneur totale en diène, tout copolymère à deux blocs (AB) présent ayant une masse moléculaire apparente comprise entre 60.000 et 100.000.
