PROPERTIES OF ASPHALT-STABILIZED AGGREGATES FROM EVALUATION OF LABORATORY PREPARED SPECIMENS

The tensile and resilient characteristics of the cold-mixed asphalt-stabilized aggregates were investigated in the laboratory using the indirect tensile and resilient modulus techniques. The mixture was also characterized by using the Marshall equipment that is frequently used in asphalt concrete mix design. Specimens were fabricated with emulsified asphalt, two aggregate types, two emulsion contents, and two initial added moisture contents. The properties of the mixture were evaluated at different curing conditions and test temperatures. Comparisons were made between dry and vacuum saturated specimens to evaluate the moisture resistance of the mixture. It was found that the mixture properties were largely affected by temperature. In addition, curing increased the tensile resistance and the resilient modulus values. Aggregate type, asphalt content, and initial added moisutre content altered the properties of the mixture at different degrees. Vacuum saturation affected the mixture characteristics to some extent. Other properties such as density, moisture content, and air voids were evaluated. (Author)
