Cationic Bitumen Emulsions

CATIONIC RAPID SETTING (CRS) – CRS-1, CRS-2
The rapid setting grades are designed to react quickly with aggregate and revert from the emulsion state to asphalt. They are used primarily for spray applications such as aggregate (chip) seals, sand seals, surface treatments and asphalt penetration macadam. CRS-2 grades have a higher viscosity to minimize potential for runoff.

CATIONIC MEDIUM SETTING (CMS) – CMS-2
The medium setting grades are designed for mixing with coarse aggregate, as these grades do not break immediately upon contact with aggregate. CMS mixes possess some measure of workability and have high viscosities to prevent runoff. These are generally used for cold mix applications and mixed-in-place operations.

CATIONIC SLOW SETTING (CSS) – CSS-1, CSS-1h
The slow setting grades are designed for maximum mixing stability. They are used with high fines content and dense-graded aggregates. All slow setting grades have low viscosities that can be further reduced by adding water. It can then be used for tack coats, prime coats, fog seals and dust palliative. CSS-1h has a stiffer/harder emulsion residue.

Lake Asphalt produces Cationic Bitumen Emulsions according to American Society for Testing and Materials (ASTM) Cationic Emulsified Asphalt specifications ASTM D2397.

ADVANTAGES OF LAKE ASPHALT’S CATIONIC BITUMEN EMULSIONS

  • Environmentally friendly and easy to use due to relatively low viscosity.
  • Applied in ambient conditions without the need for expensive heating equipment (energy saving).
  • May be used with cold as well as heated aggregates and with damp or dry aggregate, unlike cutback asphalts.
  • Low cost, road servicing alternative to cutback, superior to comparable products.
  • Easy and ready to use, already liquefied with superior performance to Cutbacks, without the shortcomings.
  • Quality adhesion and durability are equivalent to and in most cases superior to other Cold mix applications.
  • Specific Emulsions to suit your aggregate type and job requirements

    • Lake Asphalt produces Cationic Bitumen Emulsions in a state of the art continuous plant with a capacity of twelve (12) metric tons per hour, backed by technology of a world leader in the business, Akzo Nobel.

General uses of emulsified asphalt:

Only those grades of emulsified asphalt in general use have been indicated. It is possible that under variations of aggregates, climatic conditions. Or both, additional selections may be appropriate. Where the use of emulsified asphalt for applications other than those listed in the table are required, Lake Asphalt can be consulted.
