General Description of Cationic Bitumen Emulsion K1-70
RAHA Group Bitumen Emulsion K1-70 is a cationic rapid setting bitumen emulsion that contains 67% bitumen. It is a medium viscosity emulsion used mainly for tack coating in normal overlay and patching work. Bitumen emulsion K1-700 is chocolate brown in color and is a free-flowing liquid at ambient temperature and is commonly used for Tack-Coating as well. RAHA Group Asphalt Emulsion K1-70 cationic bitumen emulsion is made according to BS EN 13808:2013 standard and Malaysian Standard, MS 1.61 (1994).
Bitumen Emulsion is made up of three basic ingredients which include Bitumen, an emulsifying agent, and water. It is a well-known fact that asphalt and water will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives. Cationic Emulsions that have positively charged ions may be used at ambient temperatures with aggregates, which do not have to be completely dry. Emulsions are less hazardous to use and can be applied in a wider range of conditions and used for many applications including road surfacing. Asphalt emulsions are classified according to the electric charge that surrounds the emulsion’s asphalt particles (i.e. whether it is a cationic or an anionic emulsion) and how quickly the suspended asphalt particles separate from the surrounding water (“breaking”).
Application of Bitumen Emulsion K1-70
RAHA Group Bitumen Emulsion K1-70 containing 67% Bitumen, is commonly used for Tack-Coating. This is applied to an underlying surface to aid with the adhesion of the following asphalt layer. Bitumen Emulsion K1-70 Is also used for Fog Sealing, Mist Spraying, Concrete Curing, Grouting, Sealing, Patching, Formation, and Sub-base and Surface Dressing. Bitumen Emulsion K1-70 is a rapid setting.
Bitumen Emulsion K1-70 is primarily used as a tack coat, to provide a bond between the existing surface and overlays e.g hot rolled asphalt, macadam, and slurry seals, or between courses in road construction.
Also, one of the main application of emulsion K1-70 is in road surface treatments and seals as:
- Single surface treatment
- Multiple surface treatment
- Sand seal
Application Guidelines
- Surface treatment as surface dressings, patching, repair of potholes, and more generally road maintenance.
- It is particularly suitable for sealing unbound granular materials and roads which have been recycled.
- It incorporates specially developed adhesion agents to promote a good bond with the chippings.
- It is suitable for use in repair applications using truck-mounted Patching Units.
- It is available ex-works, delivered to customer’s tanks, or can be sprayed using RAHA Group Bitumen Emulsions fleet of sprayers.

Ambient (5°C – 35°C) or if required heated to 50°C.
Safety and Handling K1-70
- Contains petroleum distillate; flammable: keep away from open fire, sparks, or other ignition sources; wear protective clothing, gloves, and goggles.
- Fire flammable when wet, flash point 40°C.
- Skin –avoid repeated or prolonged contact, if occurs remove with hand cleaner that removes oil or grease, then clean with soap and water.
- Eyes contact could cause irritation, if contact occurs flush immediately with clean water Inhalation can cause dizziness, move immediately in fresh air if dizzy, and if breathing difficulty persists administer oxygen.
General Precautions:
Do not mix with anionic emulsions or with cationic emulsion from other manufacturers as this may cause co-agulation. This is particularly critical when spraying. If changing grade the following procedure should be followed:-
- Drain spraying equipment completely.
- Flush the machine (including the spray lance) by continuous circulation of kerosene.
- Pump the waste solution into a waste receptacle and drain completely. Dispose of in accordance with regulations. Breaks in spraying should be accompanied by periodic flushing of the lance with kerosene. At the end of each working period, it is good practice to empty completely the contents of the container, flush with Kerosene by continuous circulation and then drain.
