On décrit de nouvelles compositions aminées cationactives liquides à température ambiante, ne formant pas de concrets par maintien prolongé à des températures voisines de 0°C, ni par exposition à l'air libre, et ne contenant pas de solvants, comprenant de 20 à 80 % d'alkylétheramines à chaîne ramifiée et de 80 à 20 % d'alkylpolyamines oxyalkylées. Application de leurs solutions aqueuses acides comme phases émulsionnantes des bitumes routiers et procédé amélioré de fabrication des émulsions de bitumes routiers.

Date Oct. 5, 1989.New cation-active amine compositions, liquid at ambient temperature, which do not form concretions by prolonged maintenance at temperatures in the region of 0 DEG C., nor by exposure to the open air, and which do not contain solvents, comprising from 20 to 80% branched-chain alkyletheramines and 80 to 20% oxyalkylated alkylpolyamines. Application of their acid liquid solutions as emulsifying phases of road bitumen, and improved manufacturing process for road bitumen emulsions.
