Bituminous emulsion is liquid form of bitumen in which substantial amount of bitumen is suspended in finely divided condition in an aqueous medium; bitu-men is the dispersed phase and waters the continuous phase. MARUTI SS – 1 cationic bitumen emulsion is designed to exceed the functional requirements of respective applications.


  • To coat and bond loose mineral particles on the surface of the base course
  • To seal surface pores and make the surface of the base course water-resistant
  • To penetrate the existing base course i.e., WMM surface so as to plug the capillary voids in it
  • To harden and toughen the base course surface
  • To assist adhesion between the base and the super imposed surface course in conjunction with a tack coat


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.
