In normal atmospheric conditions, Bitumen and water can't mix and will separate instantly. Emulsifiers are specialty chemicals used to stabilize the fine dispersion of bitumen droplets in water.

The additives are used to modify the emulsion characteristics, or improve their applications. ADDIBIT are control breaking additives used in the production of micro-surfacing and slurry seal treatments, providing fluidity, quick breaking and excellent mix cohesion.

 Adhesivity is defined as the capacity of one binder to remain covering one aggregate without stripping under water or traffic requirements. Adhesion promoters improve the adhesive bond aggregate - bitumen which in turn enhances the long-term performance of the pavement.
