Asphalt emulsions, used in road construction and maintenance, may be defined as an homogeneous mixture of minute asphalt droplets suspended in a continuous water phase. These types of emulsions are usually termed oil-in-water (o/w) emulsions. Their preparation involves the use of a high speed, high shear mechanical device, such as a colloid mill.

Bitumen emulsion is a mixture of fine droplets of bitumen and water. The average range of bitumen mixed is from 40 to 70% on the total weight. Based upon the time taken by the water to evaporate, bitumen emulsion is further classified into 3 types based on setting time: Slow setting emulsion. Medium setting emulsion. Rapid setting emulsion.

An asphalt emulsion is liquid asphalt cement emulsified in water. It is composed of asphalt, water and an emulsifying agent. The emulsifying agent is sometimes called the surfactant, which is composed of large molecules. These soap molecules are like tadpoles, having a hydrocarbon tail soluble in liquid asphalt and an electrically charged or ...

other chemicals and is pumped to a colloid mill along with asphalt. The colloid mill breaks the asphalt up into tiny droplets. The emulsifying agent migrates to the asphalt-water interface and keeps the droplets from coalescing. The emulsion is then pumped to a storage tank. Asphalt emulsions are very complicated and use a lot of chemistry to ...

The main components of the emulsion are asphalt (bitumen) and water. Emulsions come in different grades but typically contain between 55 and 75 % asphalt. In addition to the asphalt and water, asphalt emulsions contain 0.1-2 % of an emulsifier or 'soap' which functions to stabilize the emulsion. These soaps are similar in nature to the ...

Good emulsion requires correct application of mechanical energy to reduce the size of bitumen particles and prevent their coalescence after dispersion. The size of the particles is defined by the colloid mill, the duration of the component's presence in the mill, concentration and type of emulsifier and the temperature of the emulsification.

Bitumen emulsions are an oil-in-water type of emulsion where the bitumen is dispersed in water. The size of the droplets is generally in the range of 0.001 to 0.01mm. The bitumen content in the emulsion depends on the intended application of the emulsion, but is rarely lower than 40% or higher than 70%.
