Bitumen emulsion plant, Bitumen Emulsion Production

Bitumen emulsions1Bitumen emulsion is a blend of fine beads of bitumen and water. were first used in Europe in the 1930s. Since then, the industry has seen many promising designs, which allowed to improve production efficiency and process, as well as product yield. At this time, bitumen emulsions of all types (anionic2The term anionic bitumen emulsion is derived from the migration of particles of bitumen under an electric field. The droplets migrate toward the anode (positive electrode), and hence the emulsion is called anionic., cationic3The term cationic is derived from the migration of particles of bitumen under an electric field also. The droplets migrate toward the cathode (negative electrode), and hence the emulsion is called cationic., water in oil, oil in water, fast, medium and slow setting) are without a doubt a promising material for various construction works. The number of processes where bitumen emulsions are used is growing.

The USB-2 bitumen emulsion units are semi-automated plants with components mounted on metal frame and connected with pipelines.

The rate of emulsion consumption depends on the type of surface treated. For asphalt surface, the consumption is 500 g/m2, in case of gravel the consumption grows to 1200 g/m2. Treatment of asphalt crumbs increases consumption up to 2000 g/m2.

Water-bitumen emulsion is a dark brown liquid. Emulsion is made by dispersing of bitumen in water with the addition of surfactants.

Bitumen emulsions are indispensable for various road construction tasks. It forms a protective layer for automobile roads (asphalt, gravel or concrete).

Bitumen emulsions. General information. Principles.

The main component of any such system is the binding. In normal conditions, bitumen is solid, therefore to mix it with mineral material, it must be made liquid by heating.

An alternative – emulsification of bitumen

The amount of solid material (bitumen) in emulsion is up to 70%. In the form of small particles it is suspended in water. General viscosity of the emulsion coincides with the viscosity of water phase; therefore it is liquid at room temperature.
