filled asphalt emulsions containing betaine emulsifier

The gilsonite-asphalt emulsion compositions of the present invention comprise a base stock consisting of a blend of gilsonite, asphalt, and a latex or rubber. Preferably the latex used is the residue after the water has been substantially removed, the base stock then being emulsified in water with an emulsifying agent.

Bitumen emulsions are normally of the O/W type although inverted emulsions based on cut-back bitumens have special applications. There is evidence that bitumen can form multiple W/O/W emulsions. Emulsions containing from

 · Asphalt Emulsions are bituminous binders that are formed by dissolution of the bitumen particles in water with the help of an emulsifier. Asphalt emulsions, which have a wide range of application such as surface treatment, tack coat, primer, etc., do not have a flash point and they are not flammable or explosive. They

James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 1.2.1.4 Asphalt Emulsion. Asphalt emulsion (emulsified asphalt), like cutback asphalt, is also designated as a liquid asphalt to distinguish this product from the typical semisolid to solid asphalt binders. It is a mixture of two normally immiscible components (asphalt and water) and an emulsifying agent (usually soap).

 · A novel betaine-type asphalt emulsifier, 3-(dodecyloxy)-2-hydroxypropan-N-carboxymethyl-N,N-dimethylammonium chloride, has been synthesized in a three-step reaction from lauryl alcohol, epichlorohydrin, dimethylamine, and chloroacetic acid. The optimum reaction conditions were obtained for synthesis of 2-(dodecyloxymethyl)oxirane in the first step. The yield reaches 75.7 % under the …

 · The amount of emulsifier in the CRS 1 type emulsion was partially replaced with Chitosan in 20% (w/w) incremental steps until it reached 80%. The CSS1 type emulsions became highly viscous when the replacement of emulsifier exceeded 20%. Therefore for the CSS1 type emulsion, the emulsifier was replaced only with 10% and 20% (w/w) of Chitosan.

For instance, a typical anionic emulsifier such as tall oil fatty acids commonly used for manufacturing of rapid-medium set type asphalt emulsions at range of 0.4 to 0.6% use levels, did not produce a stable, filled asphalt emulsion, even at 0.6% and at 1.0% use level (by weight of the emulsion).

 · Asphalt emulsions are water-continuous dispersions of fine asphalt droplets, typically 1–10 μm in diameter, manufactured with the aid of a colloid mill. The emulsions may contain between 40% and 80% asphalt by weight. The emulsions have significantly lower viscosity than asphalt itself, and so can be applied at lower temperatures.
