Anionic Bitumen emulsion RS-1 is a rapid-setting anionic asphalt emulsion designed for chip seals and Tack coat. It breaks and cures quickly, destabilizing instantly on aggregate surfaces. The emulsion grade depends on aggregate size, with medium-setting emulsions for stone mixtures and slow-breaking emulsions for sand mixtures. The emulsion’s electric charge and separation time are classified, ensuring long work ability times for dense-graded aggregates with high fines content. The product is exported to various East Asian regions, including China, Malaysia, Thailand, Taiwan, Vietnam, Philippines, Indonesia, Cambodia, and certain African countries like Congo, Djibouti, and Rwanda.

Description of Bitumen Emulsion RS-1

Bitumen Emulsion RS-1 is a rapid-setting anionic asphalt emulsion designed to break and cure quickly, destabilizing instantly on contact with aggregate surfaces. Bitumen Emulsion RS-1 is an anionic water-based emulsified asphalt with low viscosity and fast setting time containing minimum 57% bitumen designed for use as a bituminous binder for chip seals and Tack coat.

Generally, for mixtures, the choice of emulsion grade depends on the size of the aggregate, with stone mixtures requiring medium-setting emulsions and sand mixtures necessitating slow-breaking emulsions. In the case of anionic emulsions, the breaking process primarily occurs through the evaporation of water in the emulsion’s continuous phase, rendering them sensitive to temperature and humidity, which can influence their breaking properties.

Bitumen emulsion RS-1 are classified according to the electric charge that surrounds the emulsion’s asphalt particles (i.e. whether it is a cationic or an anionic emulsion) and how quickly the suspended asphalt particles separate from the surrounding water (“breaking”). A slow-setting emulsion is designed to maximize the mixing time with aggregates.
Longer workability times ensure a good coating on dense-graded aggregates with a high fines content. The setting speed of any emulsion is relative to atmospheric conditions at the time of construction.

Process of Bitumen Emulsion RS-1

1. Material Preparation:

• Bitumen: The base material is bitumen, a viscous petroleum product. It’s heated to reduce its viscosity for easier processing.
• Water: Treated water is used to ensure the quality of the final product.
  Emulsifier: Anionic emulsifiers are added to create the negative charge on the bitumen droplets.

2. Emulsification Process:

• Colloid Mill: The bitumen, water, and emulsifier are mixed in a high-shear colloid mill. This process breaks down the bitumen into tiny droplets and disperses them evenly in the water.
• Charge Development: The emulsifier creates a protective layer around each bitumen droplet, giving it a negative charge. This negative charge prevents the droplets from coalescing and stabilizes the emulsion.

3. Quality Control:

• Testing: The emulsion is subjected to various tests to ensure it meets the specified properties, including viscosity, bitumen content, setting time, and stability.

4. Storage and Transportation:

• Storage: The emulsion is stored in suitable tanks to prevent contamination and degradation.
  Transportation: It’s transported in specialized tankers to maintain its quality during transportation.

Application of  Emulsion RS-1

Bitumen emulsion RS-1, a rapid setting grade anionic bitumen emulsion has been specifically developed to provide waterproofing in construction application, on concrete and even metal surface. The high flash point and low solvent content make RS-1 an easy to use and safe product. Bitumen emulsion RS-1 can be applied by using a painting brush, squeegee, airless spray and even a roller.

Generally, bitumen emulsions are widely used in highway construction, surfacing and maintenance. They are also used in various other applications where water-repellent surfaces are needed. Rapid setting emulsions are grade of emulsions that are sufficiently stable to allow mixing with find or dusty aggregate mineral particles and further processing before setting to a coherent mass. Such grades of Bitumen emulsion RS-1, when anionic, react chemically with Portland cement constituents forming a water insoluble salt and thus possess valuable water resistant characteristics.

Advantage of Emulsion RS-1

• Water-based: Reduces environmental impact compared to solvent-based alternatives.
• Lower production temperatures: Conserves energy and reduces greenhouse gas emissions.
• Cost-effective: Often more economical than traditional asphalt materials.
• Efficient application: Can be applied using various methods, reducing labor costs.
• Rapid setting: Minimizes traffic disruption.
• Excellent adhesion: Provides strong bonds between layers.
• Versatile: Can be used for various applications (tack coats, spray patching, surface treatments).
• Improved road performance: Enhances water resistance and skid resistance.
• Easy application: Can be applied using various methods, including spraying, rolling, and brushing.
• No heating required: Simplifies the application process.
• Safe to handle: Lower risk of burns compared to hot asphalt.

While Anionic Bitumen Emulsion RS-1 is generally considered safer than traditional hot asphalt, it’s essential to follow proper safety precautions to prevent accidents and injuries.
