Bitumen SS1 is a slow-setting anionic bitumen emulsion that is typically used in a variety of applications, including tack coat for road paving, dust control, and soil stabilization. The “SS1” designation refers to the specific type of slow-setting emulsion, which is anionic in nature.
Bitumen SS1 is produced by dispersing bitumen droplets in water with the aid of an emulsifying agent. The resulting emulsion is a stable liquid that can be stored and transported easily, and can be applied to various surfaces using standard application equipment.
In road construction, bitumen SS1 is commonly used as a tack coat to promote adhesion between asphalt layers. It can also be used as a prime coat to prepare the surface of a road for the application of an asphalt layer, and as a fog seal to protect and extend the life of an existing asphalt surface.
In dust control and soil stabilization applications, bitumen SS1 can be applied to unpaved roads and other surfaces to reduce dust and improve their load-bearing capacity.
Overall, bitumen SS1 is a versatile and cost-effective product that offers a range of benefits for various applications, including improved adhesion, dust control, and soil stabilization.
Bitumen emulsion SS1 is slow-setting, anionic type and are further characterized by their ability to remain stable on storage although produced with equipment that generates a wide range of shearing forces. Such characteristics are imparted to the asphalt emulsions through the use of emulsion-conditioner compositions comprising a partially desulfonated lignosulfonate, preferably an anionic or nonionic emulsifying agent and, optionally, a thickene.
Usage of anionic emulsion bitumen SS1 is two phases of water and bitumen which is not possible to mix and first inter phase is inside of outer phase.Particle size of emulsion is 0.1 to 5 micron. In normal conditions and without emulsifier the two parts of emulsion SS1 is unstable and quickly will segregate. By adding emulsifier into water and bitumen that is alkaline salt with Ammonium Salt in high speed mixer at ISO condition making bitumen SS1.
Percentage of emulsifier is 3-5% and total water content is between 30-50%.By adding Emulsifier to bitumen and water we put anionic electron on the material and each particle of bitumen became like as circle with size of 0.001 to 0.01 mm and become floating in water. Using bitumen SS1 is environmental friendly since any flammable material or kerosene is not used and firing of the bitumen during the usage would be zero.
This kind of anionic bitumen has more adhesive to building material which is contain lime.
Cationic bitumen emulsions CSS1 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 break is completed the water must still be completely evaporated for the residual Asphalt to achieve full strength.
It is using for cold asphalt in cold or humid or sealing.Asphalt emulsions are widely used in highway construction, surfacing and maintenance. They are also used in various other applications where water repellent surfaces are needed. Slow-setting emulsions are grades of emulsions that are sufficiently stable to allow mixing with fine or dusty aggregate mineral particles and further processing before setting to a coherent mass. Such grades of asphalt emulsions (bitumen SS-1 grade), when anionic, react chemically with portland cement constituents forming a water-insoluble salt and thus possess valuable water-resistant characteristics.

Bitumen CSS1 is a type of cationic slow-setting bitumen emulsion that is used in road construction and paving applications. The “CSS1” designation refers to the specific type of cationic slow-setting emulsion, which is produced by electrostatically charging the bitumen particles to promote adhesion to aggregate.
Bitumen CSS1 is a stable liquid that can be stored and transported easily, and it can be applied to various surfaces using standard application equipment. It is typically used as a tack coat to promote adhesion between asphalt layers, but it can also be used for other applications such as fog sealing, crack sealing, and surface treatment.
Compared to anionic emulsions such as SS1, cationic emulsions such as CSS1 are generally more effective at promoting adhesion to aggregate and can be used in a wider range of conditions. However, they are more sensitive to moisture and require careful application to ensure proper performance.
Overall, bitumen CSS1 is an important component of modern road construction and paving applications, particularly in the preparation of road surfaces for asphalt layers. Its use can help to ensure the long-term performance and durability of road pavements and reduce the need for costly maintenance and repairs.
Bitumen K160 is a type of bitumen or asphalt binder used in road construction and paving applications. The “K” in the name refers to the kinematic viscosity of the bitumen, which is a measure of its flow resistance. The number “160” refers to the minimum kinematic viscosity of the bitumen in centistokes (cSt) at 60°C.
Bitumen K160 is a relatively low-viscosity binder compared to other bitumen types, making it suitable for use in areas with lower temperatures. It is commonly used in road construction projects in colder climates, where it is essential to use a binder that can maintain its viscosity and performance properties in cold weather.
Bitumen K160 can be used in a variety of asphalt mixtures, including hot mix asphalt (HMA) and warm mix asphalt (WMA), and it can be modified with various additives to improve its performance properties. It is typically available in bulk quantities and can be transported and stored easily.
Cost effective bitumen K160 is an important component of modern road construction and paving applications, particularly in areas with colder climates. Its use can help to ensure the long-term performance and durability of road pavements and reduce the need for costly maintenance and repairs.
