What Is an Asphalt Emulsion?
An asphalt emulsion is a material designed to allow asphalt to be applied at room temperature.
Since asphalt has low fluidity at room temperature, it must be heated to several hundred degrees Celsius or mixed with an organic solvent when used for road paving.
Therefore, when asphalt is used for road pavement, it must be heated to several hundred degrees Celsius or mixed with an organic solvent to increase its fluidity.
On the other hand, asphalt emulsion can be applied at room temperature without heating.
It is energy-saving and reduces CO2 emissions.
Moreover, since there is no need to mix organic solvents, there will be less generation of foul odors and environmental impact during construction.
Uses of Asphalt Emulsions
Asphalt emulsions are used, for example, in the construction of asphalt pavements.
In general, asphalt pavement consists of a roadbed formed by crushed stones and other materials on top of a roadbed (ground) and a heated asphalt mixture.
The base layer and surface layer are formed by spreading a heated asphalt mixture over the roadbed.
Asphalt emulsions are spread on the surface of the roadbed after the roadbed is formed but before the base layer is laid, and is used as a prime coat to improve the fit between the roadbed and the base layer.
When used in this manner, asphalt emulsions has other effects besides those mentioned above, such as stabilizing the roadbed and enhancing the waterproofing of the roadbed.
Asphalt emulsions may also be used as a tack coat, which is spread on the surface of the substrate after the base layer is formed but before the surface layer is laid, to improve the fit between the base layer and the surface layer.
In addition to the aforementioned applications, asphalt emulsions may also be used for surface treatment of asphalt pavements by being spread after the formation of the surface layer.
Asphalt emulsions are also widely used as waterproofing materials for structures, in addition to the aforementioned asphalt pavements.
Characteristics of Asphalt Emulsions
Asphalt emulsions are produced by dispersing fine asphalt particles in water using an emulsifier.
After spreading, the water and asphalt emulsions particles separate from each other, causing the asphalt particles to aggregate and form an adhesive film that provides strength.
The main components of asphalt emulsions are straight asphalt, water, and emulsifier, of which straight asphalt, the main component, accounts for 50% to 70% of the total.
After straight asphalt, water is the next most common component, followed by emulsifiers.
Emulsifiers are so-called surfactants, and there are three types: cationic emulsifiers, anionic emulsifiers, and nonionic emulsifiers.
Although these emulsifiers contain smaller amounts of emulsifiers than other components, their properties have a significant impact on the properties of asphalt emulsions.
As a result, asphalt emulsions are classified into the following three types according to the type of emulsifier used.
Cationic emulsions, which use cationic emulsifiers: Water and asphalt emulsions particles easily separate after spraying, allowing a film to form without waiting for the water to evaporate.
Because of its ability to quickly form a film on the surface of crushed stone, this cationic emulsion accounts for most of the asphalt emulsions used in asphalt paving.
Anionic emulsions, which use an anionic emulsifier, have the disadvantage of taking longer to form a film because it is difficult for the water to separate from the asphalt emulsions particles.
On the other hand, they have the advantage of high stability as an emulsion and can be stored for a long period of time.
Nonionic emulsions that use nonionic emulsifiers: These emulsions do not carry an electrical charge and have high chemical stability, so they can be mixed with alkaline materials such as cement.
