Abstract
A process for the preparation of bitumen-polymer compositions, characterized by the fact that the bitumens are modified by grafting of a dihalopolybutadiene polymer that serves as a receptive structure to block polymers and to elastomers co-vulcanizable with the grafted bitumen. The elastomers are selected from the group that includes linear polybutadiene-polystyrene block copolymers, a polystyrene-polybutadiene block copolymer, and a vulcanizable polynorbornene rubber. They are used as road and industrial bitumens.
