Asphalt emulsion is extensively used in pavement preservation techniques. The curing process through which the emulsion gains intended binder properties is highly influenced by the emulsion type, curing time, and temperature, and relative humidity. In the domain of cement concrete characterization, the maturity method has been used to predict strength gain under the combined effect of time and temperature. The present paper attempts to apply the maturity method to evaluate the influence of time and temperature on the curing process of asphalt emulsion. In this study, asphalt emulsion (slow-setting asphalt emulsion) was cured at different curing temperatures (120,135,150, and 165 °C) and curing times (1, 2, and 3 hours). The asphalt emulsion residue obtained after different curing conditions was tested for rheological characterization. The results indicate that the curing conditions influenced the development of the properties of the emulsion residue. The maturity as a function of equivalent age and temperature showed a reasonable trend at higher curing temperatures.
