Bitumen emulsions are usually dispersions of minute droplets of bitumen in water and are examples of oil-in-water emulsions.
The bitumen content can be varied to suit different requirements and is typically between 30% and 70%. The primary objective of emulsifying bitumen is to obtain a product that can be used without the heating normally required when using cutbacks and paving grade bitumen.
In the manufacture of bitumen emulsions, hot bitumen is sheared rapidly in water containing an emulsifying chemical (emulsifier). This produces very small particles of bitumen (the dispersed phase) dispersed in water (the continuous phase). The bitumen particles are stabilized in suspension and do not readily coalesce due to the presence of the emulsifier, which is concentrated on the surface of the bitumen particles.
During application, the water in a bitumen emulsion is either lost by evaporation, or it may separate from the bitumen because of the chemical nature of the surface to which the emulsion is applied. This process is referred to as breaking. Because bitumen has a density only slightly higher than water, sedimentation of the bitumen droplets in an emulsion during storage is very slow. Emulsions can usually be regenerated after long storage times by gentle stirring to re-disperse the bitumen droplets.
Bitumen Emulsion Grade
Bitumen emulsion is a mixture of fine droplets of bitumen and water. But as the bitumen is a petroleum product it doesn’t mix with water and as it is sticky in nature, it doesn’t easily gets disintegrated into fine droplets. To overcome this problem an emulsifier is used. Emulsifier can be defined as a surface-active agent. Emulsifier keeps the bitumen in its fine droplet state by disallowing it to mix with other droplets. As the droplets are very fine they suspend in water. Therefore, bitumen emulsion is a dispersed liquid consisting of three products, i.e. water, bitumen and emulsion. Bitumen emulsion is a mixture of fine droplets of bitumen and water.

Uses Cationic emulsions may be used at ambient temperatures with aggregates, which need not be completely dry. Emulsions are less hazardous to use and can be applied in a wider range of conditions. Advantages a) Cationic emulsions may be used at ambient temperatures with aggregates, which need not be completely dry. b) Lower costs are incurred due to a considerable saving on fuel for heating purposes. c) Operating at lower temperatures for cold mixing gives a greater margin of safety, even though these emulsions may contain fluxing oil. d) Not only may cold mix be stockpiled for long periods, but it may also be packaged in small containers and stored. This facilitates the treatment of very small areas quickly, cleanly and economically. Disadvantages A regular water supply is required and this can be a great problem in very hot countries, where water can be in very short supply.

Water-based Bitumen Emulsions and Rubberized Emulsions with 5%, 10% Rubber. Solvent-based Bitumen Primer, coatings. Bitumen Mastic sealants (Cold applied). Supply from UAE based manufacturer. Available in 15 liter, 20 liter and 200 liter packing.
Bitumen emulsion consists of three basic ingredients: bitumen, water, and an emulsifying agent. Based on specifications it may contain other additives, such as stabilizers, coating improvers, anti-strips, or break control agents. It is well known that water and asphalt will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives. Bitumen emulsions are divided into three categories in terms of setting: 1. Rapid-setting (RS) 2. Medium-setting (MS) 3. Slow-setting (SS)
BITUMEN EMULSION PLANT, BITUMEN STORAGE PLANT
Bitumen is a black, semi-solid or liquid substance with high viscosity produced by the non-destructive distillation of crude oil during petroleum refining. The core industry using bitumen is road construction (asphalt) and another significant field is the building industry (roofing membranes, water-proofing felts)
