Emulsion
Anionic Bitumen
The Anionic Emulsion is derived from the migration of particles of bitumen under an electric field. The droplets migrate toward the anode (positive electrode), and hence the emulsion is called anionic. In an anionic emulsion, there are “billions and billions” of bitumen droplets with the emulsifying agent at the water bitumen interface. active agents used in the manufacturing process govern the process in which the resulting asphalt emulsion can be used.
Anionic Bitumen emulsion in which the droplets of bitumen carry a negative charge since negatives repel each other, all the droplets repel each other and remain as distinct bitumen drops in suspension.
Cutback RC 800
Rapid Curing 800 RC800 a combination of penetration grade asphalt cement and a diluent or cutter highly rapid in its volatility making it easier to apply. Cut back RC800 is compliant with ASTM standard for cut back asphalt.
Bitumen 10/20
Bitumen 10/20 is commonly used for the production of hot mix asphalt for the base and wearing courses.
Application:
Anionic emulsions are still widely used throughout North America, Africa and Australia for a range of road maintenance techniques, including pavement sealing, gravel seals, tack coating, slurry sealing and in situ pavement recycling. Most emulsions used for such applications in Europe are cationic. Anionic emulsions are also used as a waterproofing material in the construction industry worldwide (e.g. for roofing applications).
