Abstract:
1. A method for improving the resistance to aggressive chemical agents of a cross-linked bitumen/polymer composition comprising from 1 to 10% by mass of a crosslinked aromatic monovinyl hydrocarbon and conjugated diene copolymer, with respect to the mass of the cross-linked bitumen/polymer composition, in which said aromatic monovinyl hydrocarbon and conjugated diene, copolymer has a content of 1,2 double bond units originating from the conjugated diene, comprised between 5% and 50% by mass, with respect to the total mass of the conjugated diene units and using 2 to 6% by mass of Fischer-Tropsch waxes, with respect to the mass of the cross-linked bitumen/polymer composition.
