asphalt-rubber binders may be used, such as AR Type II or Type III The choice of binder is dependent on material, traffic, and environmental factors The first consideration is to use hot applied AC binders or asphalt emulsion binders AC binders are asphalt, while emulsions are approximately 2/3 asphalt and 1/3 water.

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 viscosity for lower.

Asphalt emulsion, as used in road construction and maintenance, is a homogeneous mixture of minute asphalt droplets suspended in a continuous water phase (Dybalski, 1976) The preparation of these oil-in-water (o/w) emulsions involves use of a high-speed, high-shear mechanical device, such as a colloid mill which breaks down molten asphalt into.
