EFFECT OF EMULSIFICATION CONDITIONS ON STORAGE STABILITY OF HIGH VISCOSITY MODIFIED ASPHALT EMULSION

Abstract

Abstract: The effects of preparation conditions such as emulsion temperature and emulsifier solution, outlet pressure of colloid mill, emulsifier content as well as SBS content in modified asphalt on the storage stability of high viscosity modified asphalt emulsion (HVMAE) were investigated. The relations between average size of high viscosity emulsified asphalt and storage stability were studied by laser particle analyzer. The results show that the storage stability of HVMAE firstly decreases and then increases as emulsion temperature and SBS dosage increases, but reduces first followed by a slow decline trend with the increase of outlet pressure of colloid mill, indicating a positive relations of storage stability with average particle size. Under the optimum conditions: SBS modified asphalt at 165 ℃， emulsifier solution temperature of 55 ℃, outlet pressure of colloid mill 0.2 MPa, dosage of emulsifier 0.4% and SBS content in modified asphalt 3.2%, the prepared HVMAE was applied successfully in overhaul project for Beijing West Chang'an Avenue in 2014 and 2016.

Key words: high viscosity modified emulsified asphalt, storage stability, average particle size, SBS, viscosity
