Bitumen Emulsion
Bitumen emulsions generally belong to the oil-in-water type of emulsions where bitumen is dispersed in water with the aid of a small quantity of emulsifying agent. The agent stabilises the bitumen particles under normal conditions of storage. Bitumen emulsions derive their main use in road construction and maintenance because of their safety, ease in handling and excellent adhesion properties.
Advantages: The advantage of water based bitumen emulsion is that it allows bitumen, which is semi-solid unless heated, to be handled and applied at low temperatures. Following application of an emulsion, it undergoes a ‘breaking’ or ‘setting’ process where the bitumen droplets combine to deposit the bitumen on the paving aggregate as a film. By contrast, cutback bitumen contains a significant proportion of cutter (kerosene), to reduce the viscosity of the bitumen and help coat the aggregates. The cutter must then evaporate before the bitumen is left behind as a film on the stone. This evaporation process can take many months. If the cutter is still present when the final surfacing is applied, this can result in flushing of the pavement and resultant loss of surface texture and skid resistance.
