Emulsified Asphalt - Pavement Interactive

When the asphalt cement starts to adhere to the surrounding material (aggregate, existing surface, subgrade, etc.) the color changes from brown to black (Figure 2) and the emulsion is said to have "broken" (Figure 3). As water begins to evaporate, the emulsion begins to behave more and more like pure asphalt cement.
