Plant for bitumen emulsion production

What is a emulsion Production Unit?

A bitumen emulsion production unit is an industrial facility (fixed, mobile, or containerized) designed to manufacture bitumen emulsions used in road impregnation (tack coats, surface dressings) and for the production of emulsion aggregates (cold mix of aggregates and emulsion for structural or base layers).

Key Features

• Versatility: These units produce different grades of emulsions (cationic, anionic, modified or unmodified) suitable for impregnation, bonding, surface coatings, cold-poured asphalt, or the manufacture of emulsion-based aggregates.

• Production Capacity: Depending on the model, capacity ranges from 6 to 40 tons/hour, continuous or batch, with equipment suitable for both one-off needs and large-scale industrial production.

• Mixing Technology: The heart of the plant is the mill, which ensures fine shearing of the bitumen in the aqueous phase, ensuring the stability and fineness of the emulsion.

• Precise Dosing: The bitumen, soap, and emulsifier pumps are motorized and variable-frequency, allowing for precise and reproducible dosing, essential for the quality of the finished products. Automation: Modern units are controlled by an automated control system, facilitating operation, traceability, and safety, while requiring minimal personnel.

• Mobility: Many models are designed as compact or containerized modules, easily transportable for use on different construction sites.

Main Applications

• Road Impregnation: Production of emulsions for tack coats, primers, surface dressings, and crack treatment.

• Emulsion-Based Mixing: Production of binders for cold mixes of aggregates and emulsions, used in base or reinforcement layers for pavements, particularly during reprofiling or rehabilitation work.

Technical and Environmental Benefits

• Cold Use: Reduced energy consumption and CO₂ emissions.

• Increased safety during storage and transportation.

• Production flexibility and adaptation to different types of construction sites (new construction, maintenance, recycling).

• Consistent and reproducible quality thanks to automation and control of production parameters.

A modern bitumen emulsion production unit can effectively meet the needs of road impregnation and the production of emulsion gravel, thanks to its versatility, its dosage precision, its adapted production capacity and its ease of transport and use on site.
