KEY FEATURES
-
Improved workability: It can be applied at lower temperatures and has a lower viscosity, which reduces the risk of delays in the construction process.
-
Reduced environmental Impact: Bitumen emulsion is water-based and emits fewer harmful fumes and gases during the application, making it a more sustainable choice for road construction.
-
Enhanced performance: Bitumen emulsion is more resistant to water damage and can be applied more easily in colder temperatures, making it a more versatile and reliable material for road construction.
-
Safer for workers: Bitumen emulsion does not require heating or other high-temperature processes during the application, which reduces the risk of accidents and injuries for workers.
-
Lower overall cost: Bitumen emulsion is more cost-effective to produce, transport, and apply than traditional bitumen, which can help reduce the overall cost of road construction projects.
Description
APPLICATION METHOD
APPLICATION
Although Road Primer are typically sprayed cold, they can be heated to ___°C 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 Road Primer 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
Road Primer 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
Road Primer 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 Primers are often used in conjunction with aggregate materials of varied sizes to maintain the proper rolling resistance. For example, in a double surface treatment, crushed quarry materials with broken faces and less wear are commonly employed.
Storage Conditions
Store under cover out of direct sunlight and protect from extremes of temperature. In tropical climates the product must be stored in an airconditioned environment. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging.
