The asphalt emulsion is an unstable system in terms of thermodynamics. Sedimentation, flocculation, and coalescence will occur as a result of the storage period, temperature, and contact medium, finally leading in demulsification (Hesp et al., 1991). Emulsion stabilizers are used to prevent these storage-related problems. However, some stabilizers may become depleted over time and lose their effectiveness, resulting in more frequent removals and replacements of the product. Asphalt emulsion is a mixture of water and oil. The stability of this mixture depends on several factors such as type of oil, amount of water, pH value, etc. Asphalt emulsion is usually stable at temperatures below 120°F (49°C). Above this temperature, the oil component will begin to break down and sediment will start to form. If the mixture is not stirred regularly, it may also cause corrosion to metal containers. Corrosion is the loss of metal from its original structure due to chemical action of fluids on the surface. Corrosion can be classified as either exogenous or endogenous. Exogenous sources include soil, air, moisture, and other substances that come into contact with metals. Endogenous sources include chemicals produced by body tissues itself. Corrosive substances can alter the appearance of metals through oxidation or rusting. They can also change the color of non-metallic materials such as wood, paint, and plastics.
