What are bituminous emulsions and their applications?

Bituminous emulsions are stable mixtures of bitumen and water, used extensively in road construction and maintenance. Applications include surface dressing, where they provide a protective layer over existing pavements; tack coats, which enhance adhesion between pavement layers; and cold mix asphalt for road repairs. They are also used in microsurfacing and slurry seals to fill minor cracks and improve surface texture. Bituminous emulsions are favored for their ease of application, energy efficiency, and environmental benefits, such as reduced emissions and lower energy consumption during application.
