A laboratory investigation was performed to characterize cold mixed asphalt emulsion treated bases. Indirect tension, resilient modulus, Hveen and water damage techniques were used in the mixture evaluation. The effects of aggregate type and gradation, added moisture content, asphalt emulsion content, and temperature were determined. The mixture was characterized at different curing conditions in the field. The effect of temperature on the tensile and resilient characteristics of the mixture is apparent. In addition, curing increases both the tensile strength and the resilient modulus of the mixture. Reasonable correlations are found between the indirect tensile test and the resilient modulus test results. Vacuum saturation has some effect on the tensile and the resilient properties of the mixture. Other asphalt emulsion mixture properties such as density, retained moisture content, and air voids are evaluated
