OPTIMISING BITUMEN PERFORMANCE

The actual performance of the bitumen depends on the total performance of a bitumen/ aggregate mixture which again depend as the design of the mixture, the way it was mixed and how it was laid and compacted.

SPECIFICATION OF PENETRATION GRADE BITUMEN

Cutback Bitumen’s we supply MC-30 & MC-70

Cut Back Bitumen’s are categorized into slow curing, medium curing and rapid curing types and they are blends of penetration bitumen with solvents such as kerosene used in spraying and some mixing applications. Normally base bitumen is used for producing is bitumen 80/100 Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed Sealing with neat bitumen. The materials used to cutback bitumen will evaporate after application to leave the remaining material similar in hardness to the original bitumen.
MEDIUM-CURING MC-30, MC-70 PRIME COAT

Bitumen Emulsions we supply cationic Slow Setting and cationic Rapid setting Emulsions.

Bitumen Emulsion CSS-1,CRS-1 & CRS-2.

Bitumen emulsion is a combination of three basic ingredients, Bitumen, water, and small amount of an emulsifying agent. These ingredients are introduced into a process which shears the bitumen into tiny droplets. Bitumen emulsions are classified in to two product groups such as slow setting and rapid setting.

Advantages of Bitumen emulsions

a) Cationic emulsions may be used at ambient temperatures with aggregates, which need not be completely dry.

b) Lower costs are incurred due to a considerable saving on fuel for heating purposes.

c) Operating at lower temperatures for cold mixing gives a greater margin of safety, even though these emulsions may contain fluxing oil.

d) Not only may cold mix be stockpiled for long periods, but it may also be packaged in small containers and stored. This facilitates the treatment of very small areas quickly, cleanly and economically.


EMULSION APPLICATIONS

SPECIFICATION


TACK COAT

A tack coat is a very light spray application of diluted asphalt emulsion. It is used to create a bond between an asphalt overlay being placed and the existing surface. A tack coat is recommended for all overlays

PRIME COAT

It has been typically spray applications of low viscosity asphalt on granular base in preparation for placing an asphalt mixture. A prime coat performs several important functions
