Two-Coat Surface Dressing with Cationic Bitumen Emulsion
Binder
The binder specified for this application is Cationic Bitumen Emulsion Rapid Setting 2 grade complying with IS: 8887 2004
First Coat
Application of Binder
The Cationic Bitumen Emulsion should be sprayed uniformly on the prepared base by a mechanical sprayed or cans. While using spray cans the holes should be of 6 mm diameter spaced at 30 mm apart to prevent clogging.
Rate of Application
For the first coat, rate of application of emulsion should be 1.2 to 1.4 kg/M2. Application of aggregates immediately after spraying of emulsion, 13.2 aggregate should be spread uniformly covering the surface completely and evenly followed by rolling.
Second Coat
Second Coat of surface dressing may be applied on the same day as the first coat. However, the second coat should be before one hour after the rolling of the first coat. Traffic should not be allowed on the first coat before application of the second coat.
Application of Binder
The aggregates of the first coat may appear loose and unbounded at a few places. However, these should not be disturbed because the same will get bonded after breaking or setting of emulsion, the cationic bitumen emulsion should be sprayed uniformly on the prepared base by a mechanical sprayer or spraying cans.
Rate of Application
For the second coat, rate of application of emulsion should be 1.6 to 1.8 kg/M2.

Open Grade Premix Carpet with Cationic Bitumen Emulsion
Binder
The binder specified for this application is Cationic Bitumen Emulsion Rapid Setting 1 for tack coat, medium setting grade for premix carpet and slow setting grate for premix seal coat complying with IS: 8887 2004. For liquid seal coat Medium Setting grade may be used but use Rapid Setting grade is preferable.
Application of Binder (Tack Coat)
The Cationic Bitumen Emulsion should be sprayed uniformly on the prepared base by a mechanical sprayed or cans. While using spray cans, the holes should be of 6 mm diameter spaced at 30 mm apart to prevent clogging. The range for spraying temperature for emulsion should be 20 to 70 C. The tack cost should be left to cure till all volatiles have evaporated. On water Bound Macadam surface, water should be sprayed before applying tack coat.
The rate of application of emulsion for carious surface should be as under.
Normal Bitumen Surface (Existing black top) | 0.20 to 0.30 kg/M2 |
Dry and hungry Bitumen surface | 0.25 to 0.35 kg/M2 |
Granular surface treated with primer | 0.25 to 0.30 kg/M2 |
Granular surface (non-primed) | 0.35 to 0.40 kg/M2 |
Cement Concrete surface | 0.25 to 0.40 kg/M2 |
Rate of Application of Binder
For 20 mm premix carpet, the emulsion should be used at the rate of 2.0 to 2.3 kg/M2
Seal Coat with Cationic Bitumen Emulsion
Application of Binder
The Cationic Bitumen Emulsion should be sprayed uniformly on the prepared base by a mechanical sprayer or cans. While using spray cans, the holes should be of 6 mm diameter so as special at 30 mm apart to prevent clogging.
Rate of Application of Blinder
For premix seal coat, the Emulsion should be used at rate of 1.0 to 1.2 kg/M2
Application of Aggregates
Immediately after spraying Emulsion, stone chips in a clean state should be applied uniformly so as to cover the surface completely followed by rolling.
Rate of Application of Aggregates
For liquid seal coat crushing fine aggregates of 6.7mm should be done in a cold making 0.006M3 per M2
