Lignin quaternary ammonium salt complex asphalt emulsifier complex formulation technology optimization
N-[2-hydroxy-3-octadecyl amino] propyl trimethyl ammonium chloride (A) is respectively compounded with lignin quaternary ammonium salt (B) to obtain complex emulsifier AB, when the complex emulsifier AB dosage is 0.4% of the total amount of emulsified asphalt, and the emulsifier A / B (molar ratio) is 0.7 / 0.1, the emulsified asphalt has good storage stability, and the emulsified asphalt can be widely used in the adhesive layer, fog seal layer, non solvent cold mixing, recycling for asphalt and asphalt pavement substrate stabilizing.
