Abstract

Il est possible d'incorporer de manière stable au bitume des polymères styréniques normalement incompatibles en recourant à un copolymère élastomère à trois blocs solubilisé ou compatibilisé dans la phase bitumineuse. Ledit copolymère, une fois incorporé à la phase bitumineuse continue présente des domaines polystyréniques dispersés dans le bitume, ou une unité réceptrice qui stabilise le polystyrène particulaire et l'empêche de se dissocier du bitume.
