Abstract
Engineering properties, including Marshall stability, indirect tensile strength, and tensile stiffness modulus have been carried out on alkylbenzene Sulphonate- modified asphalt paving mixtures. In this study, four percent of alkylbenzene sulphonate by weight of asphalt were used at optimum asphalt content which was by Marshall method.
obtained The result indicated that 2% of alkylbenzene sulphonate is effective in improving the indirect tensile strength properties, while other percents slightly improved these properties. Results also indicated that the addition of alkylbenzene sulphonate to asphalt reduced the fluidity temperature of asphalt by 8% at 2% of alkylbenzene sulphonate, this phenomenon is more economical in the asphalt plant and not consuming time for heating of asphalt in storage tank.
