Asphalt / Bitumen Emulsifiers for High-Performance Road Construction and Maintenance
What are Asphalt and Bitumen Emulsifiers?
Asphalt and bitumen emulsifiers are chemical agents that enable bitumen to be dispersed in water, forming stable emulsions used in road construction and maintenance. These emulsions are widely uses in road construction and maintenance applications to improve handling, application, and adhesion of bitumen to aggregates.
How Emulsifiers Work in Asphalt Systems
Emulsion Formation and Stability
Emulsifiers allow bitumen to be broken into fine droplets and dispersed in water, creating a stable emulsion. This stability is critical for storage, handling, and transport prior to application.
Adhesion and Coating Performance
Emulsifiers also enhance the interaction between bitumen and aggregates, improving coating, adhesion, and overall pavement performance across a range of materials and conditions.
Benefits of Asphalt Emulsifiers
Improved Adhesion to Aggregates
Enhanced bonding between bitumen and aggregates helps improve pavement durability and resistance to moisture damage.
Enhanced Stability and Storage Performance
Well-formulated emulsions maintain stability during storage and transport while breaking effectively during application.
Efficient Application and Processing
Emulsions enable easier handling, uniform application, and improved processing across a variety of paving and maintenance techniques.
Applications in Road Construction and Maintenance
Asphalt emulsifiers are used across a wide range of pavement applications, including:
- Chip seal
- Micro-surfacing and slurry seal
- Tack coat and bond coat
- Fog seal
- Cold mix asphalt
- Recycling applications such as CIR, CCPR, and FDR
These technologies are often used alongside asphalt additives and advanced pavement technologies to support a complete pavement performance strategy.

Arkema understands the challenges associated with asphalt and bitumen emulsions, where stability during storage must be balanced with the ability to break and build strength quickly after application. Poorly performing emulsions can lead to reprocessing, increased costs, and reduced paving efficiency. We offer a broad range of asphalt and bitumen emulsifiers, including ACRA™, ArrMuls®, Dinoram®, Polyram™, Stabiram®, and Emulsamine® (EU), designed to enhance both the physical and chemical properties of emulsions across a wide range of applications:
