Specification of Cationic Bitumen Emulsion as IS:8887:2004:
Application of Bitumen Emulsion:
Cationic Rapid Setting -l(Tack Coat):
Tack Coat is a very light spray application of diluted bitumen emulsion to create a bond between an bitumen overlay being placed and the existing surface.
The functions performed by Tack Coat are
>> It is essential for good patching operation
>> To avoid skidding of top layer from bottom layer
>> To add strength to both the layers as it makes both
layers act as one.
Cationic Rapid Setting-2 (Surface Dressing):
Four types of surface dressing are commonly adopted using Bituminous emulsions, they are :
>> Single layer surface dressing
>> Racked in surface dressing
>> Double layer surface dressing
>> Sandwich surface dressing
The various techniques are explained in the picture beside
Cationic Medium Setting (Maintenance):
Changing weather conditions and heavy traffic deteriorate the quality of Bituminous pavements, hence it is necessary to ensure pavement upkeep in order to maintain good traffic, safety and comfort conditions for users. Commonly used maintenance tech-niques are
>> Patching >> Surface Dressings
>> Slurry Seal >> Cold Mix Concrete
Patchwork is the most technique adopted for maintenance in our country.
Patching is a technique used for :
>> Pothholes >> Hollows
>> Surface damage >> Cracks etc..
Cationic Slow Setting - 1 (Prime Coat):
Prime coat typically is application of low viscosity bitumen over a granular base, preparing it for laying an bitumen mixture on it. A prime coat performs several important functions.
>> Coats and bonds loose material particles on the surface of the base.
>> Hardens or toughens the surface of the base.
>> Waterproofs the surface of the base by plugging capillary or interconnected voids.
>> Provides adhesion or bond between the base and the bitumen mixture.
Specially designed emulsion for prime coat. Suitable for slurry seal, premix seal coat and fog spray. Application of Bitumen Emulsion SS-2 to an absorptive surface,
designed to penetrate, bond and stabilize this existing surface.
