Bitumen Emulsion RS-2
General Description of Anionic Bitumen Emulsion RS-2
Bitumen Emulsion RS-2 is a rapid-setting anionic asphalt emulsion designed to break and cure quickly, destabilizing instantly on contact with aggregate surfaces.
Bitumen Emulsion RS-2 is an anionic water-based emulsified asphalt with high viscosity and fast setting time containing minimum 57% bitumen designed for use as a bituminous binder for chip seals. It is chocolate brown in colour and is a free-flowing liquid at ambient temperature.
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”). A slow-setting emulsion is designed to maximize the mixing time with aggregates.
Longer workability times ensure a good coating on dense-graded aggregates with a high fines content. The setting speed of any emulsion is relative to atmospheric conditions at the time of construction.
General product feachers
- Seals narrow cracks against moisture penetration
- Traffic can be restored very shortly after application.
- Excellent for use in the early spring and late fall
- Effective bond/tack prevents slippage planes between
- pavement layers.
- Ideal for use with small, portable spray units
Application of Anionic Bitumen Emulsion RS-2
Anionic emulsion is obtained by an electric field. In an anionic emulsion, the droplets migrate from the anode. Anionic bitumen emulsion RS-2 is a slow setting, anionic type of bitumen. The particle size of the emulsion is 0.1 to 5 micron and the emulsifier which is usually used for producing anionic Asphalt Emulsion RS-2 is alkaline salt with Ammonium Salt which puts the bitumen and water droplet together.
RECOMMENDED USE
RAHA GROUP Bitumen Emulsion RS-2 is ideally suited for surface dressing, grouting, and penetration macadam.
Application Guidelines
- Clean asphalt surface and treat oil spots prior to
- application to ensure proper adhesion.
- Do not apply if precipitation is anticipated.
- Do not dilute the product with any cutter stock or water.
- The spray rate is dependent on the application type.
- Contact RAHA GROUP Marketing representative for application temperature guidelines.
Recommend rate of Application
Tack Coat RS-2 cationic bitumen emulsion can be used at ambient temperature at the spray rate of 0.25 to 0.70 litre per square meter (0.05 to 0.15 gallon per square yard).
Packaging, Storage and Handling RS-2
- RS-2 should be stored in bulk tanks, ideally vertical to minimize surface area
- Do not allow RS-2 to either freeze or boil: it will break. Safe storage temperatures range from 10°C (50°F) to 85°C (185°F).
- In bulk storage, mix the RS-2 every 1 to 2 weeks (more frequently in cold weather). Mixing may be done by paddle agitator (slow), loose gear pump, slow centrifugal pump, or another suitable low shear pump.
- Do not bubble air through RS-2 to agitate it: this creates excessive foam and may cause the RS-2 to break
- Always use clean storage containers. Make sure prior contents are compatible with RS-2 or the emulsion may break
- Only use approved and sealed containers for sampling the emulsion.
