Bitumen emulsions are usually dispersions of minute droplets of bitumen in water and are examples of oil-in-water emulsions. The bitumen content can be varied to suit different requirements and is typically between 30% and 70%. The primary objective of emulsifying bitumen is to obtain a product that can be used without the heating normally required when using cutbacks and paving grade bitumen. In the manufacture of bitumen emulsions, hot bitumen is sheared rapidly in water containing an emulsifying chemical (emulsifier). This produces very small particles of bitumen (the dispersed phase) dispersed in water (the continuous phase). The bitumen particles are stabilised in suspension and do not readily coalesce due to the presence of the emulsifier, which is concentrated on the surface of the bitumen particle.
As per application requirement, we supply various types of Cationic Bitumen Emulsions like Slow Setting, Medium Setting & Rapid Setting. Slow Setting Emulsion is used in slurry seal, fog seal, road mixes, prime coat applications. Medium Setting Emulsion is used for repair work/ surface dressing/ penetration macadam. Rapid Setting Emulsion is used for surface dressing, grouting & tack coat applications
Bitumen emulsions are suitable for sprayed sealing using methods similar to those used for bitumen sealing.
Bitumen Emulsions are used for tack coating prior to asphalt overlaying
Bitumen emulsion is used as primer seal which is an application of binder and aggregate cover which is intended to take traffic for a short period (up to 12 months) prior to the application of a final surface.
Bitumen Emulsions are used in Surface enrichment.
It is the light application of bituminous binder to an existing seal to replace binder lost due to oxidation and weathering effects
Various maintenance tasks may be undertaken with bitumen emulsions, for example, repair of potholes and edge breaks and for crack sealing.
