Three novel bis-cationic asphalt emulsifiers were synthesized by two steps reaction of N-tallow-1,3diaminopropane, methyl acrylate, sodium hydroxide and chloroacetic acid. The structure of the product was confirmed by FTIR, 1 H NMR and elemental analysis. The emulsifier exhibits satisfactory emulsification. The prepared bituminous emulsion showed higher storage stability. The emulsifier belongs to medium-set and slow-set asphalt emulsifier. It can be designed to perform in a wide variety ofdoi:10.1051/matecconf/201713004004 fatcat:mtshzxzqrjdd3pblktdgqdufle
