Title (EN) METHOD FOR PREPARING A BITUMEN/POLYMER COMPOSITION WITH IMPROVED PROPERTIES
(FR) PROCEDE DE PREPARATION D'UNE COMPOSITION BITUME / POLYMERE PRESENTANT DES PROPRIETES AMELIOREES
Abstract:
(EN) A method for producing a bitumen/polymer composition with ductility greater than or equal to 80 cm and ductility after RTFOT ageing greater than or equal to 45 cm, said method comprising: - providing a bitumen base, - mixing the bitumen base with • 1 to 10% by mass of elastomer relative to the mass of the bitumen base, the elastomer being chosen from SBS elastomers and elastomer mixtures comprising at least 40% by mass of SBS, • a sulfur-containing crosslinking agent, S denoting a monovinyl aromatic hydrocarbon group and B denoting 1,3-butadiene.
(FR) Procédé de fabrication d'une composition bitume/polymère présentant une ductilité supérieure ou égale à 80 cm et une ductilité après vieillissement RTFOT supérieure ou égale à 45cm, ce procédé comprenant : - La fourniture d'une base bitume, - Le mélange de la base bitume avec • 1 à 10% massique d'élastomère par rapport à la masse de la base bitume, l'élastomère étant choisi parmi les élastomères de type SBS et les mélanges d'élastomères comprenant au moins 40% massique de SBS, • un agent réticulant soufré, S désignant un groupement hydrocarboné monovinylaromatique et B désignant le 1,3-butadiène.
