BITUMEN EMULSION

Bitumen Emulsion is a mixture of Bitumen and water and emulsifier (a surface active agent). Since bitumen cannot be mixed with water, it needs to add an emulsifier with water before adding bitumen. Emulsifier comforts breaking of bitumen into minute particles and keeps it dispersed in suspension. To produce the bitumen emulsion, water is mixed with a proper emulsifying agent. Then add bitumen with the water-emulsifier mix. The amount of bitumen to be added with water can be from 40% to 70% depends on bitumen emulsion uses.

Bitumen emulsions make it easy to handle, store, transport, and apply bitumen at a lower temperature. Since this type of bitumen is liquid, there is no need to heat it before application. Moreover, applying bitumen emulsions using cold techniques reduces the consumption of energy and makes road construction environmental friendly.

  • RAPID SETTING - RS1

Rapid setting - RS1 bitumen emulsion is water based bitumen emulsion with low viscosity and fast setting time. RS grade bitumen emulsion is designed to react quickly with aggregate and revert from the emulsion state to bitumen. RS1 grade is mainly used for tack coat application. Rapid Setting strictly as per IS 8887:2017. It  is suitable as binder for penetration macadam and sand seal. This chemical is processed using supreme class chemical compounds as per the set industry norm under utmost favorable condition.

  • SLOW SETTING - SS1

Slow setting - SS1 bitumen emulsion is specially designed oil based bitumen emulsion with low viscosity and extended setting time. It is mainly used for Prime Coat and manufactured strictly as per IS 8887:2018. This chemical is processed under the utmost favorable condition keeping in industry standards. To ensure its quality, this chemical is stringently tested on various parameters. Generally SS1 used for fog seal. crack seal, & prime coat.

Features:
 

  • Superior penetration into miniature pores of sub bases

  • Easy spray

  • Extended breaking

  • Penetrate the cracks & crevices and impart strength to the layers

  • Low temperature curing

  • Prevents permeability of atmospheric air to the bottom layers

  • High adhesive properties

  • Binds loose aggregates together strongly

  • Prevents raveling and rutting

  • Water resistant and enhances easy drainage of water

  • Compatible with Portland cement

  • Better shelf life

  • Better particle size distribution

  • Extended setting time

Application:
 

  • Cationic bitumen emulsion to an absorptive surface (like low to medium high Porosity Wet Mix Macadam or Water Bound Macadam), designed to penetrate, plug the capillary voids in the surface, bond and stabilize the existing surface and to promote adhesion between it and the construction course that follows.

  • The pavements having inadequate priming of Wet Mix Macadam/Water Bound Macadam may have lesser life due to non-achievement of properties, as mentioned above.

  • MEDIUM SETTING - MS

Medium-Setting - MS bitumen emulsion is designed for mixing with coarse aggregates and is ideal in premix. Product is so formulated that is does not break immediately upon contact with aggregates and provides few minute of workable time for fixing aggregates. This type of emulsion is highly recommended for surface dressing work. It is manufactured strictly as per IS 8887:2018. Our bitumen is processed using sophisticated technology and quality tested chemical compound in conformity with the predefined industry standards.

Features:

  • No heating required

  • Environment friendly

  • Economical

  • Ease in application

  • Bond with existing surface

  • Least interference with traffic

  • Bonds well to cool, damp surfaces

  • Low temperature cure

  • Stable patches

  • Resistance to peel off under traffic

  • Resistance to stripping by water

  • Minimal preparation time for surface repair

  • Instant setting and fast development of strength

  • Better shelf life

  • Good adhesion properties

  • Better particle size distribution

Application:

  • Medium setting - MS is used for plant or road mixes with coarse aggregates minimum 80 percent, all of which is retained on 2.36 mm IS Sieve and practically none of which pass 180 microns IS Sieve, and also for surface dressing and penetration macadam.

Other Details:
 

  • Maintenance Mix: This high quality material now makes it possible to fill pot holes or carry out patch repair with open graded cold premix made on-site. The methods typically used for the repair of pot holes using asphalt emulsions are throw-and-roll and full-depth removal and replacement. All of these methods involve placing cold mix in the pot hole with a shovel and compacting with a truck tire, vibratory plate compactor or steel wheeled roller.

  • Premix Carpet: For economical and fast construction of wearing course, emulsion is used for Premix Carpet. Ministry of Road Transport & Highway (MORT&H) has also recommended use of emulsion for this application in their clause 506.2. A tack coat is applied on the cleaned surface. The cold mix is prepared as per the above method and spread over the existing surface followed by either liquid seal coat or a premix seal coat.
