Abstract

New cation-active amine compositions, liquid at ambient temperature, which do not form concretions by prolonged maintenance at temperatures in the region of 0.degree. 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.
