General Description of Anionic Bitumen Emulsion SS-1h

Anionic Bitumen emulsion SS-1h 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.

For anionic and emulsions, there are several grades of different breaking characteristics. Rapid-setting emulsions are used for surface dressing, while medium or slow-setting emulsions are used for ‘mixtures’, that is mixed with aggregate either in concrete-type mixers or in situ. Rapid-setting emulsions are not used for mixtures because they would tend to set during the mixing process and clog the mixer. Generally, in making mixtures, the finer the aggregate used, the slower setting the emulsion that has to be used. Therefore, stone mixtures require medium-setting emulsions and sand mixtures require a slow-breaking emulsion. With anionic emulsions, the breaking process is predominantly by evaporation of the water in the emulsion continuous phase. Because of this, anionic emulsions are susceptible to temperature and humidity in terms of their breaking properties.

An Anionic emulsion has a negative charge, most of the things in the world are Anionic and that is why the majority of Research and Development, formulating, and lab testing has been done in the Industrial Coatings Industry to make coatings from Anionic systems. When an Anionic emulsion is mixed with a Cationic emulsion a strong bond develops and the result is the changing of the substance to a solid. This result is not ideal to be used as a coating because it cannot be applied to substrates.

Usage of anionic bitumen emulsion SS-1h is two phases of water and bitumen which are not possible to mix and the first interphase is inside of outer phase. The particle size of the 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 the alkaline salt with Ammonium Salt in the high-speed mixer at ISO condition making bitumen SS-1h.

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 the size of 0.001 to 0.01 mm and become floating in the 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.

Application of Anionic Bitumen Emulsion SS-1h

Anionic Bitumen Emulsion SS-1h, with its slow-setting properties, is widely used in various road construction and maintenance applications. Some common applications include:

• Prime Coating: SS-1h is applied as a prime coat to prepare the base surface before paving with asphalt. Its slow-setting nature allows for better penetration and bonding to the base course.
• Tack Coat: Used between asphalt layers to promote adhesion and prevent slippage. SS-1h provides a strong bond between the existing pavement and the new layer being applied.
• Fog Seal: Applied to aged asphalt surfaces to rejuvenate and protect them from oxidation and moisture intrusion. SS-1h helps to seal small cracks and surface imperfections, extending the life of the pavement.
• Dust Control: Sprayed on unpaved roads to minimize dust generation and improve road safety. SS-1h forms a stable surface layer that reduces dust emissions and prevents erosion.
• Chip Seals and Micro-surfacing: SS-1h is used as a binder in chip seals and micro-surfacing applications to waterproof and protect road surfaces. Its slow-setting properties ensure proper adhesion and durability of the surface treatment.

Feature/Benefits of Asphalt Emulsion SS-1h

Anionic Bitumen Emulsion SS-1h offers several features and benefits that make it a preferred choice for various road construction and maintenance applications:

• Slow-setting Properties: SS-1h has a slow-breaking time, allowing for better penetration and adhesion to road surfaces. This results in improved bonding between layers and enhances the overall durability of the pavement.
• Excellent Binding Capability: SS-1h serves as an effective binder in various applications such as prime coating and tack coating, promoting adhesion between asphalt layers and preventing slippage.
• Versatility: SS-1h can be used for a wide range of applications, including prime coating, tack coating, fog sealing, dust control, chip seals, and micro-surfacing, making it a versatile choice for road maintenance and construction projects.
• Enhanced Durability: The slow-setting nature of SS-1h allows for thorough penetration and bonding, resulting in a more durable and long-lasting pavement surface.
• Environmentally Friendly: SS-1h is water-based, making it environmentally friendly compared to solvent-based asphalt materials. It also requires lower application temperatures, reducing energy consumption and emissions during construction.
• Improved Safety: By minimizing dust generation on unpaved roads and providing a stable surface layer, SS-1h contributes to improved road safety for drivers and pedestrians.

Packaging, Storage and Handling SS-1h

Packaging, storage, and handling of Anionic Bitumen Emulsion SS-1h should follow similar guidelines to those of other asphalt emulsions:

• Packaging:SS-1h is typically packaged in sealed containers such as drums or totes to prevent contamination and evaporation during transportation and storage.
• Storage: Store SS-1h in a cool, dry place away from direct sunlight and heat sources. Extreme temperatures should be avoided to prevent degradation of the emulsion. It’s essential to keep the containers tightly sealed when not in use to maintain product integrity.
• Handling: When handling SS-1h, wear appropriate protective equipment such as gloves and goggles to avoid skin contact and eye irritation. Before use, the emulsion should be agitated or stirred to ensure uniform consistency. Follow manufacturer guidelines for dilution and application rates to achieve desired results.
• Spills and Cleanup: In the event of spills, promptly clean up using absorbent materials and dispose of them according to local regulations. Empty containers should be rinsed thoroughly before disposal.
