bitumen emulsion

Bitumen emulsion is a solution of bitumen in water by emulsification is stable and tar in the water is prevented from settling.
The bitumen emulsion was recorded in 1922 by Hugh Allan Mackie.

At that time there were many thriving automotive industry and a large number of road was already known.
Now that it has passed more than 80 years of development of this technology is still the best technology for road construction.
Despite the advantages of this method still does not use it properly in our country and the implementation of new methods need complete information not provided in the technical community.
In this article, we will discuss our complete product and brief history of its use, especially in Europe and also in combination with other methods and new approaches and introduces new technologies. In addition to its advantages over other technologies, production mechanisms, procedures, and types of emulsions such as hot, cold emulsion, the emulsion is recycled and applications such as surface modeling, surface, concrete, asphalt and ... discussed.
The emulsion is formed from a system with two immiscible phases. One of the two phases as small globules or balls in the other phase is dispersed. That is fuzzy little balls, called the internal phase and fuzzy balls spread around the external or continuous phase known as phase per Amv.lsyvn different ways you can specify that one continuous phase and one other phase joined. For example, in an emulsion of "oil-in-water" non-continuous oil phase and water the continuous phase forms. Bitumen emulsion of oil-in-water emulsions in general of the non-continuous phase Bashndk·h small tar balls were scattered in the water
