PROCEDE DE PREPARATION D'UN LIANT BITUMINEUX ET SON UTILISATON DANS UN ENROBE
The present invention relates to a process for preparing a bituminous binder, based on bitumen(s) and on at least one olefinic polymer bearing at least one epoxy functional group, characterized in that added to the bitumen-polymer mixture is a basic adjuvant, selected from an imidazole or a tertiary amine having three alkyl radicals, consisting of a basic compound capable of promoting a chemical bond between the bitumen and the olefinic polymer bearing at least one epoxy functional group, said adjuvant representing between 0.01% and 5% by weight of the bitumen-polymer mixture. It also relates to a bituminous binder comprising the bitumen(s), the aforesaid olefinic polymer and the aforesaid basic adjuvant and also the use of the latter for the preparation of a bituminous mix.
