Performance Grade Bitumen

Performance Grade Bitumen

Emulsion Grade Bitumen Emulsion grade bitumen, as the name suggests, is bitumen that has been emulsified with water and an emulsifying agent. This process creates a stable suspension of bitumen droplets in water, allowing for easier handling and application in various construction and maintenance projects. Emulsified bitumen is advantageous because it can be used at lower temperatures compared to hot bitumen, which requires more energy and resources to heat. Types of Emulsion Grade Bitumen

  1. Anionic Emulsion (AE) Anionic emulsion bitumen is negatively charged. It is typically used for surface treatments, chip sealing, and slurry sealing. Due to its adhesive properties, AE bitumen is excellent for holding small-sized aggregates together, which is vital for road preservation and rehabilitation.
  2. Cationic Emulsion (CE) Cationic emulsion bitumen is positively charged. This type is widely used for more substantial projects such as road construction and repair. CE bitumen is known for its rapid setting time, making it a suitable choice for high-traffic areas and urgent repairs. It offers good adhesion and cohesion, ensuring the durability of road surfaces.
  3. Polymer Modified Emulsion (PME) Polymer-modified emulsion bitumen incorporates polymers to enhance its performance. This type of emulsion is particularly valuable in regions with extreme weather conditions. PME provides improved resistance to rutting, cracking, and moisture damage, making it suitable for demanding applications such as airports and heavy-duty pavements.
  4. Quick Setting Emulsion (QSE) Quick-setting emulsion bitumen is designed for applications where fast curing is essential. It is ideal for road repairs, as it can be applied, compacted, and opened to traffic within a matter of hours. This type is commonly used for pothole repair and small-scale road maintenance.

Applications of Emulsion Grade Bitumen Emulsion grade bitumen finds use in a wide range of applications, including:

  1. Road construction and maintenance
  2. Pavement preservation
  3. Waterproofing and roofing
  4. Seal coating and surface treatments
  5. Soil stabilization
  6. Gravel road dust control
