Installations for production of bitumen emulsion

The emulsion can be defined as disperse system in which one of liquids is distributed in the form of small drops in other liquid. Bituminous emulsions belong to oil emulsions in water where bitumen is distributed in water. Content of bitumen is defined by intended application of emulsions, but usually fluctuates within 30 - 70% . Scope of bituminous emulsions in road construction is very wide, bituminous emulsions are applied for:

• Surface treatment;
• Soil strengthenings;
• As a binding layer;
• Productions of cold mixes;
• Dust binding;
• Slurry consolidation;
• Crushed - stone covering with impregnation;
• Zaplatochny mixes;
• Fillings of cracks.

Installation for production of a bituminous emulsion can be periodic or continuous action. At implementation of technological process solution of emulsifier and bitumen pass through a colloidal mill where there is an emulsification. Solution of emulsifier and bitumen move in a mill pumps. Solution of emulsifier contains water, emulsifier, acid and if it is required, the stabilizer which carefully mix up in the ratios providing uniform solution with the correct indicator rn. The main advantages of installations of continuous action in comparison with those of periodic action are:

• Bystry transition from one type of an emulsion to another;
• Decrease in costs for a rabsila and operational costs;
• Almost the health hazard connected with use of chemicals is completely excluded;
• The increased efficiency.
