RS_2_CATIONIC_BITUMEN_EMULS

MARUTI RS-2 cationic bitumen emulsion is more viscous liquid with higher binder content and is most suited for applications such as:

  • Surface dressing
  • Grouting
  • Penetration macadam
  • Sand seal

Applications

Surface Dressing:
It consists of application in one or two coats, each consisting of a layer of bituminous binder sprayed on a previously prepared base, followed by a cover of stone chips rolled in to form a wearing course. RS-2 type cationic bitumen emulsion is ideal for surface dressing on the shoulders and for protection of freshly laid base course. Typical rate of application for two coat surface dressing as per (MORT&H) clause 510.2 is 28-32 kg/10 sq. m.

Grouting:
For economical construction of low volume roads, a combined base and wearing courses can be made by an application of MARUTI RS-2 cationic bitumen emulsion on the laid and compacted aggregates. This application can be carried out even when the stone layer is damp.

Penetration Macadam:
It consists of construction of one or more layers of compacted crushed coarse aggregates with alternate application of bituminous binder and key aggregates to be used as base course on roads, subject to the requirements of the overall pavement design.

Sand Seal:
A bituminous sand application for existing pavement surface to seal the surface and to function as a light-wearing course.
