Abstract

Two kinds of multi-amine imidazoline E1 and E2 are synthetized as asphalt emulsifier by the long-chain organ-ic acids and polyethylene polyamine. The purpose of adjusting the mixing time of asphalt emulsion and aggre-gate can be achieved by controlling the head group number of hydrophilic group. The research results show that the synthetic emulsifier with excellent surface performances; critical micelle concentration (CMC) of E1 and E2 are 0.0728 mmol.L-1 and 0.1508 mmol.L-1 under 25 , respectively. The surface tension cmc are 23.47 mN.m-1 and 28.50 mN.m-1 under the CMC. The addition of the head group of hydrophilic group makes the CMC and cmc increase. The particles of asphalt emulsions prepared by two kinds of emulsifiers are uniform. The volume average particle size are respectively 2.56 m and 2.33 m. The increase of amidogen head group number of hydrophilic group is conducive to extend mixing time. the mixing time with the aggregate of the asphalt emulsion prepared by E1 and E2 are respectively 65s and 146s.
