| This study evaluated the laboratory properties of asphalt binder and mixture modified with SPC(Sulfur Polymer Cement), which consists of sulfur as a main ingredient that is an industrial by-product made from refining process of crude oil and carbon-black as an additive. Four levels of SPC modifier ratios(0, 10, 30, 50%) were evaluated in the laboratory. Superpave(Superior Performing Asphalt Pavements) system was used to determine the PG(Performance Grade) and evaluate the property of SPC modified binder at the different temperatures. IDT(Indirect Tensile Test) was performed to evaluate the resistance of fatigue and low-temperature cracking at $10^{circ}C;and;-10^{circ}C$. Wheel-tracking test was also performed to evaluate the rutting-resistance of SPC modified asphalt mixtures. Test results showed that the more SPC modifier ratios, the better rutting-resistance and the more potential of low-temperature cracking resistance. However, SPC modifier did not show the effect on the fatigue cracking resistance. |
