Some grades of bitumen are ideal for hot methods of road building, whereas others are suitable for cold techniques. Because the viscosity of bitumen emulsion manufactured is lowered in cold road building procedures, there is no need to heat it before application. When the temperature is chilly or a bituminous spray is required, low viscosity bitumen is highly suggested.
Bitumen emulsion and cutback bitumen are two well-known forms of bitumen supplied by Bitumen emulsion manufacturers that are ideal for cold procedures; nevertheless, their applications and benefits vary. In what follows, we will throw some light on the application of bitumen emulsion.
What is the purpose of bitumen emulsion?
Bitumen emulsions were introduced by Bitumen emulsion manufacturers to the industry in the twentieth century, primarily for spray applications; however, they are now employed in road construction and pavement maintenance for both mixing and spraying. In the next sections, we will go through bitumen emulsion applications, including preventative and corrective maintenance.
Bitumen Emulsion Varieties and Their Applications
Various features of bitumen emulsion should be addressed to make a road surface more durable. We examine bitumen emulsions to categorise them based on viscosity, particle electrical charge, and setting type. Following is an explanation of the uses of bitumen emulsion based on the results of significant tests:
- Application based on viscosity level
The results of viscosity testing must be consulted when deciding on the optimal grade of bitumen emulsion for your specific application.
A lower viscosity of bitumen emulsion is required for dense graded aggregates; while, a thicker viscosity of bitumen emulsion is required for open graded aggregates to obtain an acceptable thickness.
- Application based on setting type
When applying bitumen emulsion to a surface, selecting the proper setting type is critical.
Because rapid setting emulsion sets fast when it comes into contact with aggregates, it is widely utilised in low-surface road applications, notably chipseals and surface treatment.
In the premixing of bitumen emulsion and coarse aggregate, especially open graded mixtures, medium setting emulsion is recommended by the bitumen emulsion manufacturers.
Slow-setting emulsion takes a long time to dry. As a result, it may be combined with aggregates having a large surface area. They are the most stable emulsion kind and may be utilised in dense graded aggregate bases, slurry sealing, and asphalt recycling.
- Emulsion particle application based on electric charge
Bitumen emulsions are always evaluated in terms of particle electrical charge by the Bitumen emulsion manufacturers.
A particle test charge causes bitumen emulsion to be classified into two types: anionic and cationic. Some aggregates work better with anionic bitumen emulsion, whereas others work better with cationic bitumen emulsion.
Conclusion:
Bitumen emulsion is a chemical reaction that occurs between bitumen, water, and an emulsifying agent in the production facility of Bitumen emulsion manufacturers. This liquid bitumen is more efficient for road building than regular bitumen, especially at lower temperatures.
Using emulsified bitumen as a low temperature approach may also help to reduce emissions and energy usage. The energy required to build a road using bitumen emulsion (cold-mix bitumen) is roughly half that required to build a road with hot-mix bitumen.
