Abstract
Cationic emulsions of bituminous binders of the type consisting of an organic phase formed of a bituminous binder dispersed in an aqueous phase containing a cationic emulsifying agent and an acid. The bituminous binder is a bitumen-polymer type binder and the acid present in the aqueous phase is a possibly hydroxylated mono or polycarboxylic acid, used in sufficient quantity that the pH of the said aqueous phase is comprised between 1 and 7. The bituminous binders of the bitumen-polymer type having passed through the said emulsions present an excellent aging behavior.
