Title
(EN) BITUMEN/POLYMER COMPOSITION WITH AN ADHESIVE STRENGTH PRESERVED DURING STORAGE AT HIGH TEMPERATURE AND PROCESS FOR ITS PREPARATION
(FR) COMPOSITION BITUME/POLYMERE PRESENTANT UNE ADHESIVITE SE CONSERVANT AU STOCKAGE A TEMPERATURE ELEVEE ET PROCEDE DE PREPARATION D'UNE TELLE COMPOSITION
Abstract
(EN)
The bitumen/polymer composition contains a bitumen and, based on the bitumen weight, 0.5 to 15 % of a polymer, 0.05 to 10 % of an adhesive-carrying component of the amine, amide or imidazoline type, and possibly 1 to 30 % of a flux agent, the adhesive-carrying component being grafted onto the polymer present in the composition. Said composition is produced by putting the above-mentioned ingredients of which it is composed in contact with each other, at a temperature of between 100°C and 230°C and agitating them in the presence of a coupling agent which provides free element-like or radical-like sulphur. Application: production of coverings such as road surface coverings, coated materials and sealing coverings.
(FR)
La composition bitume/polymère renferme un bitume et, en poids du bitume, 0,5 à 15 % d'un polymère, 0,05 à 10 % d'une composante adhésiphore du type amine, amide ou imidazoline et éventuellement 1 à 30 % d'un agent fluxant, la composante adhésiphore étant greffée au polymère présent dans la composition. Cette composition est obtenue par mise en contact des ingrédients précités la composant, à une température entre 100°C et 230°C et sous agitation, en présence d'un agent de couplage fournissant du soufre libre élémentaire ou radicalaire. Application de la composition à la réalisation de revêtements tels que revêtements superficiels routiers, d'enrobés ou de revêtements d'étanchéité.
