Asphalt emulsion is used in various road construction processes due to its versatility and ease of application. It acts as a binder in cold mix asphalt, surface treatments, and pavement maintenance. In surface dressing, it provides a thin protective layer that seals the pavement and enhances skid resistance. In cold mix applications, asphalt emulsion binds aggregates without the need for high temperatures, reducing energy costs and environmental impact. It is also used for tack coats to ensure proper adhesion between pavement layers. The use of asphalt emulsion leads to faster project completion and improved road performance.
