Description Of Bitumen Emulsion CSS-1
specially designed water-based Bitumen Emulsion with low viscosity and extended setting time makes it an ideal product for prime coating on highly porous surfaces. It is dark brown in color and is a free-flowing liquid at ambient temperature.
Bitumen emulsion consists of three basic ingredients: bitumen, water, and an emulsifying agent. Based on specifications it may contain other additives, such as stabilizers, coating improvers, anti-strips, or break control agents. It is well known that water and asphalt will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives. Bitumen Emulsions CSS-1 have a positive charge and hence a direct and very rapid reaction between the emulsion and an aggregate or pavement is possible.
The size of the charge or the Zeta potential affects stability, the larger the charge the greater the repulsion, but as the aggregate is negatively charged the higher the zeta potential the more rapid the reaction. So it is possible to stabilize a cationic emulsion in the same way that makes it a more rapid break. The other mechanism of evaporation is available too but as the emulsion is stabilized this form of break becomes slower. Thus a balance must be struck. After the electrostatic part of the reaction is complete the emulsion will rely on flocculation and coalescence to complete break.

After the break is completed the water must still be completely evaporated for the residual Asphalt to achieve full strength.
Bitumen Emulsion CSS-1 is cationic bitumen emulsion containing minimum 57% bitumen. It’s specially designed water based Bitumen Emulsion with low viscosity and extended setting time that makes it an ideal product for prime coating on high porous surfaces. It is dark brown in color and is a free flowing liquid at ambient temperature.
Application of Bitumen Emulation CSS-1
Cationic Bitumen Emulsion CSS-1 can be used successfully for tack coats, fog seals, and as a dust suppressant. Long workability times make it ideal for dense graded emulsion base mixes and base stabilization. One non-paving use is the mulch treatment of soil that has been seeded and fertilized. While general guidelines can be given for selecting emulsions, laboratory testing is strongly recommended. There is no substitute for a laboratory evaluation of the emulsion and the aggregate to be used. Different types and quantities of the emulsion should be tried with the aggregate to find the best combination for the intended use. An experienced technician can determine the type and grade of the emulsion to be used.
