Electrical properties of bitumen emulsions

Fuel, 1995
The complex dielectric constant (permittivity) of water-in-bitumen emulsion was measured for emulsions with water volume fractions ranging from 0 to 0.5, in steps of 0.1. Significant departure from theoretical calculation was observed, and was attributed to the presence of polar components in the bitumen.

Waterproofing latex-bitumen emulsions

Polymer Science. Series D, 2008
Bitumen emulsions are developed based on new anionic emulsifiers, which are wastes of chemical industry. Optimal concentrations of emulsifiers in bitumen emulsions are established. The developed bitumen emulsions are not inferior in their process and service parameters to known domestic and foreign analogs.

ATOMIZATION CHARACTERISTICS OF BITUMEN CRUDE-WATER EMULSION

Atomization and Sprays, 1998
Measurements of the angular patterns of scattered light were carried out on sprays of an emulsion of bitumen crude (70% by weight) in water produced by a home-built air-assisted atomizer at different air flow rates. The size distribution of the bitumen droplets was previously measured by optical microscopy.

Effect of process parameters on bitumen emulsions

Chemical Engineering and Processing: Process Intensification, 2005
Abstract Bitumen emulsification experiments have been carried out in a continuous pilot scale rotor-stator facility. The effects of the following process parameters, namely the temperature of the aqueous phase and bitumen, the rotor speed, the dispersed phase content, the bitumen grade and the emulsion flow rate were investigated.
