Abstract (en)
[origin: WO2017178753A1] 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.
