Bitumen EmulsionWhat is Emulsion?Today the main use of bitumen emulsion is in the road making industry for construction and maintenance. Bitumen emulsions are a dispersion of bitumen in an aqueous continuous phase, stabilised by the addition of an emulsifier. They are prepared as emulsions at high temperatures, but applied as solid dispersions at ambient temperatures. In road making, bituminous products are typically applied with mineral aggregate/stone. The strong adhesion that occurs between the bitumen emulsion and mineral aggregate/stone enables the bitumen emulsion to act as a binder, with the mineral aggregate/stone providing mechanical strength for the road. Bitumen alone is difficult to work with, at ambient temperatures since it is a highly viscous material under these conditions. It can, however be transformed into a workable state by blending with petroleum solvents or by emulsification with a surfactant in water to form a bitumen emulsion. Emulsified bitumen acts as a key tool in road maintenance and construction technology as it combines amazing versatility while offering multiple comparative advantages.
