More Information
Summary:A modified asphalt composition contains a bituminous component, a copolymeric thermoplastic elastomer (TPE), a high-cis homopolymeric polybutadiene rubber (BR) and a cross-linking agent. The modified asphalt composition exhibits improved low temperature flexibility (crack resistance), improved resistance to rutting (deformation) and/or improved storage stability. Une composition d'asphalte modifiée contient un composant bitumineux, un élastomère thermoplastique copolymère (TPE), un caoutchouc polybutadiène homopolymérique à haute teneur en cis (BR) et un agent de réticulation. La composition d'asphalte modifiée présente une flexibilité à basse température améliorée (résistance à la fissuration), une résistance améliorée à l'orniérage (déformation) et/ou une stabilité au stockage améliorée.
