Emulsified Asphalt – Pavement Interactive

Emulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent (such as soap). The emulsifying agent assists by imparting an electrical charge to the surface of the asphalt cement globules so that they do not coalesce (Roberts et al., 1996 [1]).Emulsions are used because they effectively reduce asphalt
