Rapid Setting 2

Bitumen Emulsion Rapid Setting 2 (PBI CRS -2)

It is specially recommended for surface dressing work due to high content of bitumen & also highly viscous liquid.

GRADE RS-2 is normally used for

Surface Dressing
Grouting Purpose
Penetration Macadam

Advantages:

Reduced cost of maintenance
It is very economical & easy application
Low temperature curing
Highly adhesive properties
Water resistant & enhances easy drainage of water
This prevents lateral movements of structural layers.
Make more strengthen layer and prevents from water ingress.

Surface dressing :

It consist of application in one or two coats, each consisting of a layer of bituminous binder sprayed on previously prepared base, followed by a cover of stone chips rolled in to form a wearing course. RS2 type emulsion is ideal for surface dressing on the shoulders and for protection of freshly laid base courses.

Surface Type	Qty in kg per 10 m sq. Area
1. Two coat surface dressing	28-32

Sand seal :

It is use as a bituminous sand on paving surface to seal the surface & to function as a light wearing course.

Grouting:

It is applicable also for stone layer is damp, use for low grade roads by combination of base & wearing courses with RS 2 emulsion on the laid & compact aggregates.
