ABSTRACT:
This invention relates to improved bituminous emulsions, specifically to cationic medium-set and slow-set mixing grade emulsions. More particularly, it relates to emulsifying compositions which can be used to produce bituminous emulsions exhibiting high viscosity and low asphalt residues. The emulsifying compositions are combinations of fatty amine and/or polyamine, lignin, and nonionic surfactant. A preferred emulsifying composition can be produced by reacting the combinations of fatty amine and/or polyamine, lignin, and nonionic surfactant with formaldehyde.
