Although bitumen emulsions are typically sprayed cold, they can be heated to 60ºC to increase fluidity. The fundamental advantage of using bitumen emulsion is its ability to be applied cold, although the product’s aqueous phase defines its slow or fast-breaking property. Followings are the main application areas of bitumen emulsion:
Tack coat
A tack coat is a film of bitumen applied between the two bituminous layers in the
road construction process. Applying one layer of bitumen emulsion as a tack coat between the two bituminous layers of surface courses aids in the bonding of the two layers and prevents them from slipping. This application requires a Cationic Rapid Set (RS) or Cationic Slow Set (SS) bitumen emulsion. A tack coat is also applied to the surface of an old, worn-out road before covering it with a new layer of asphalt.
Prime coat
Bitumen emulsions are also used as prime coats due to their low viscous state to bind the granular aggregates of the base course. The good fluidity of bitumen emulsions helps them penetrate the base layer and create a light, protective bituminous layer on the base course, which helps in good bonding between the non-bituminous base course and the surface course made of asphalt concrete. The prime coat also prevents moisture ingress and ensures a stable, adherent surface layer.
Seal coat
Bitumen emulsions as seal coats are applied on the surface layer to protect against moisture and provide a long-lasting barrier. Seal coats also make the road more skid-resistant yet keep the surface smoother.
Also, road emulsions are often used in conjunction with aggregator materials of varied sizes to maintain the proper rolling resistance. For example, in a double surface treatment, 3/8″ and 3/4″ crushed quarry materials with broken faces and less than 25% wear are commonly employed.
APPLICATION NOTES/WARNINGS:
-
Use of gum boots, gloves, goggles, and nose covers is recommended.
-
Keep adequate ventilation during application of the mix.
-
The emulsion barrels should be rolled well on the ground and thereafter the contents must be mixed thoroughly with a rod before drawing the emulsion for use.
-
The cover should be replaced properly after drawing emulsion from the drum.
-
Brushes, Sprayers, etc. should be cleaned thoroughly with water before emulsion sets on them.
-
No brushing over emulsion is to be done after it has turned black.
-
If it rains before the emulsion has set, spread the aggregate and wait until the surface is dry before rolling and opening to traffic.
-
On no account should workmen be allowed to walk over uncovered area where Bitumen Emulsion has been applied.
-
Do not heat and do not use them under frosty weather or in case of heavy downfall.
-
Do not open to traffic unless emulsion is broken and top surface has turned black.
-
Never mix two types of emulsion as this will cause coagulation.
ECOLOGY, HEALTH & SAFETY
• Avoid contact with skin / eyes, and avoid swallowing.
• Ensure adequate ventilation and avoid inhalation of vapor.
• Wear suitable protective clothing, gloves and eye protection.
• In case of skin contact, rinse with plenty of clean water, then cleanse with soap and
water. Do not use solvent to clean the contacted area.
• In case of eye contact, wash with plenty of clean water and seek medical advice.
• If swallowed, seek medical attention immediately. Do not induce vomiting.
