Asphalt emulsion is the combination of three common ingredients: water, asphalt, and an emulsifying agent. During the process, these components are introduced to a mechanism known in the field as a colloid mill, a machine designed to shear the asphalt into tiny droplets. The emulsifier, a surface-active agent, will keep the droplets in a stable suspension and control the breaking time with the result being a liquid product that can then be used in the regular application of road construction and maintenance.
Why Emulsions?
Asphalt emulsion is a substance with no requirement for a petroleum solvent to turn it into a liquid and it can be used without added heat in most cases. Both of these factors help to reduce energy usage during work and thus drive prices for using the product lower so that states and cities may better make use of their road maintenance budgets. Additionally, it offers a great deal of flexibility in application because it offers a variety of characteristics found only in this option, such as being environmentally friendly and being nearly completely clean of hydrocarbon emissions.
How New?
Companies such as Highline Pavement Maintenance continue a tradition created in the 20th century that is now utilized on all corners of the globe. The use of asphalt emulsions is even now continuing to grow and as much as 20% of all asphalt is used in the form of an asphalt emulsion. Compared to some construction methods, this is significantly beneficial and cost-effective and it is one of the most modern options available today.
Classification
Asphalt emulsions are classified into three categories: cationic, anionic, and non-ionic. The first two refer to the electrical charges found on the asphalt particles and these classifications become more complex from there. The best thing that you can do for yourself is to contact a reputable company for insight into the material and which classifications best fit your construction needs.
