Patent
CA 2675960
The invention relates to a bituminous composition that comprises a major portion of at least one bitumen and a minor portion of at least one chemical additive, said additive being an organogelling agent that generates a network of hydrogen bonds between the organogelling molecules constituting the same, and trapping the bitumen phase up to a maximum temperature TR of between 40 and 120°C. The invention also relates to the use of these bitumen compositions in the field of road applications, particularly in the production of road binders, as well as in industrial applications. The invention also relates to a method for preparing these bituminous compositions.
L'invention concerne une composition bitumineuse comprenant une partie majeure d'au moins un bitume et une partie mineure d'au moins un additif chimique ledit additif étant un organogélateur créant un réseau de liaisons hydrogène entre molécules organogélatrices le composant, et emprisonnant la phase bitume jusqu'à une température TR maximale comprise entre 40 et 120°C. L'invention concerne également l'utilisation de ces compositions bitumineuses dans les domaines des applications routières, notamment dans la fabrication de liants routiers, et dans les domaines des applications industrielles. L'invention concerne aussi le procédé de préparation de ces compositions bitumineuses.
