Abstract

Des compositions liantes renfermant un liant bitumineux et un modificateur de rhéologie sont divulguées. Le modificateur de rhéologie comprend un mélange dester de polyol et une composante dacide gras libre en C8-C24. Des compositions dasphalte renfermant les compositions de liant modifié sont également divulguées. Les modificateurs de rhéologie aident à améliorer les propriétés à haute température des liants bitumineux sans sacrifier le rendement à basse température. Les liants modifiés et les compositions dasphalte accroissent lutilité de lasphalte récupérée, y compris les bardeaux dasphalte récupérés et le pavage dasphalte récupéré, aidant ainsi lindustrie de la construction routière à réduire son recours aux produits vierges, non renouvelables.
