Asphalt Emulsions are bituminous binders formed by dispersing bitumen particles in water with the help of emulsifier. Asphalt emulsions have a wide application area such as surface dressing, tack coat, primer, etc.. They are not flammable and explosive. In addition asphalt emulsions are economical and environment friendly. They consume less energy and have less gas emissions. As they are applied at low temperatures, they extend the working season.
