| Abstract: | Three novel bis-cationic asphalt emulsifiers are synthesized by two steps reaction of N-tallow-1,3-diaminopropane,methyl acrylate and sodium chloroacetate which is prepared by sodium hydroxide and chloroacetic acid. The chemical structures of the bis-cationic asphalt emulsifiers are confirmed by FTIR,1H NMR and elemental analysis. The three emulsifiers have excellent emulsification effect to AH-90 asphalt. The manufactured bituminous emulsion has excellent storage stability. The bis-cationic asphalt emulsifier belongs to medium and slow-set. The medium-set asphalt emulsifier can be designed to perform in a wide variety of applications including tack coat,fog seal,and solventless cold-mix applications such as recycling and base stabilization in asphalt pavement construction. The slow-set asphalt emulsifier can be used in slurry-seal and micro-surfacing pavement construction. |
