High performance emulsion applications ... - Asphalt magazine

Asphalt emulsions are widely associated with more routine applications like tack coats and seal treatments. These treatments, locally referred to as seal coats, use a specific emulsion, a CHFRS-2P, which is a cationic, high float, rapid set emulsion with a polymer additive. It is a combination of polymer-modified emulsion, high quality

Bitumen SS1-H. Bitumen SS1h are slow-setting, anionic type of asphalt emulsions manufactured according to specifications of ASTM D977 - “Standard Specifications for Anionic Emulsified Asphalt.” It is a dispersion of small droplets of penetration grade asphalt cement in water with the aid of an emulsifier. The size of the droplets is normally in the order of 1-20 microns, with some

emulsions and occasionally also cationic emulsions may not have sufficient adhesion to aggregates, in which case adhesion promoters can be added to the bitumen or to the finished emulsion. Asphalt peptizers The emusifiability of bitumens varies. Emulsion quality can sometimes be improved by treating the bitumen with an asphalt peptizer.

9.2.1 Asphalt Emulsion Asphalt emulsions are defined in Chapter 2 of this advisory guide as dispersions of asphalt in water stabilized by a chemical system. In the case of slurry surfacing systems (like slurry seal and microsurfacing), the emulsion may be cationic or anionic; however, cationic emulsions are the most common.

Top seal dispersants and emulsion stabilisers for asphalt

Asphalt emulsions. Borregaard's lignin based emulsion stabilisers are used for anionic asphalt emulsions to reduce viscosity and water content. They are commonly used in anionic slow setting emulsion types (AESS). Our lignin based products can be made compatible with cationic asphalt emulsions through use of compatibilisers.

Tests on Bituminous Emulsions | Controls Group

Tests on Bituminous Emulsions. Bitumen emulsion is a dispersion of bitumen and water, with a cationic or anionic emulsifying agent. The bitumen content in the emulsion is around 60% and based on the mix stability, the emulsion can be Rapid Setting (RS), Medium Setting (MS), or Slow Setting (SC). Different types of emulsions require different

Heteroflocculation of a Cationic Oil-in-Water Emulsion

The use of asphalt emulsions for road fabrication is rapidly gaining in importance mainly due to energy savings, less environmental impact, and better properties of the final product. However, the formulation of these emulsions still requires a better understanding, particularly concerning their breaking phenomena. When a cationic model emulsion is contacted with a solid having a negative
