Breaking can also occur if the emulsion is packed into a smaller area by sedimenting or setting. b) CATIONIC Cationic emulsions have a positive charge and hence a direct and very rapid reaction between the emulsion and an aggregate or pavement is possible (figure 10).

Emulsified Asphalt - Pavement Interactive

As water begins to evaporate, the emulsion begins to behave more and more like pure asphalt cement. Once all the water has evaporated, the emulsion is said to have "set". The time required to break and set depends upon the type of emulsion, the application rate, the temperature of the surface onto which it is applied and environmental conditions (TRB, 2000 [2] ).
