<p>The invention relates to a fluid additive composition for bitumens and to a process for preparing the same. According to the invention, the fluid additive composition for bitumens comprises a mixture of N-substituted alkylamides, a mixture comprising polyethylene polyamines, hydroxyethyl polyethylene polyamines with 2...6 nitrogen atoms and diethanol amine, a mixture of N-substituted ammonium salts and water. The process for preparing the fluid additive composition for bitumens consists in subjecting a mixture comprising polyethylene polyamines, hydroxyethyl polyethylene polyamines with 2...6 nitrogen atoms and diethanol amine to the reaction of incomplete thermal condensation, at temperatures of 110...160A C, for 1...4 h, with a mixture of C12-C18 natural, saturated and unsaturated, fatty acids, where the molar ratio between the mixture of polyethylene polyamines, hydroxyethyl polyethylene polyamines with 2...6 nitrogen atoms : diethanol amine : mixture of C12-C18 natural, saturated and unsaturated, fatty acids is 1.1 : 1...3 : 1.</p> |
