Bitumen Emulsion RS-2

Description

Bitumen Emulsion RS-2 Description

Bitumen Emulsion RS-2 is an anionic, rapid setting bitumen emulsion, and its main uses is as a surface treatment and sealer. It is made by dispersing a bituminous material in water, employing a selected emulsifying agent to create a stable waterborne product, which can be applied without the need for preheating. The Bitumen Emulsion RS-2 is suitable to set rapidly

and then come together to create a sticky bitumen layer on the aggregate surface or pavement surfaces. binding the chipping in place, sealing imperfections or coating the surface to a thin thickness. It is important because of that product’s easy use and the ability to rapidly set after direct contact with aggregate or pavement.

Bitumen Emulsion RS-2 Properties

Its type is Anionic, Rapid Setting (RS family) and It has A smooth, black water based mixture with fine bitumen particles appearance.

Bitumen (solids) Content: Typically, the solids fraction of bitumen emulsions lies between 55%–65% by weight exact content depends on the manufacturer and grade.

Setting Behavior: Rapid breaking on aggregate designed to form a continuous bitumen film quickly after application.

Temperature Sensitivity: Because the emulsion is water borne, it reduces the need for heating and is safer and more energy efficient than cutback or hot binders.

Environmental or Safety Benefits: Low VOCs (evaporation is mainly water), lower energy demand for application versus solvent based binders.

Bitumen Emulsion RS-2 Uses

Bitumen Emulsion RS-2 is appropriate for a range of surface treatment and maintenance operations:

Surface Sealing or Fog Sealing: Rapid film formation makes RS-2 ideal for sealing aged pavements and improving surface cohesion.

Prime and Tack Applications: Used as a bonding tack coat where quick tack development is required prior to laying aggregates.

Surface Dressing (chip seal) and Slurry Treatments: Works well when immediate adhesion between bitumen and chipping is desired to minimize loss of chips.

Cold Mix and Pothole Patching (factory or field mixes): Can be mixed into cold asphalt mixtures and repair mixes where heating is impractical.

Bitumen Emulsion RS-2 Advantages

Energy and Cost Efficiency: No need for extensive heating saves fuel and reduces operational cost compared with hot binders or cutbacks.

Rapid Setting or Fast Reopening: RS-2’s rapid break helps speed construction and traffic reopening, reducing disruption on busy routes.

Better Environmental Profile: Minimal solvent emissions (water is the continuous phase), lowering air emissions during application.

Stick Well to Damp Surfaces: Emulsions tolerate some moisture on aggregates or pavements, improving application flexibility.

Versatility: Suitable for multiple maintenance operations (sealing, tack, chip seal), making RS-2 a cost effective stock item for contractors.
