Abstract
This study aimed to enhance the specifications of asphalt pavement by using sulfur waste (bloudan) resulting from sulfur purification in the Al-Mishraq sulfur mine through thermal treatment, in addition to using a mixture of sulfur waste and polyethylene glycol in asphalt modification. The study began by analyzing the chemical composition of the waste using thermogravimetric analysis (TGA), followed by treating the asphalt with different ratios of sulfur waste (bloudan). Then, the optimal ratio of polyethylene glycol was determined and treated with the asphalt, followed by using 1% of polyethylene glycol with different ratios of bloudan in asphalt modification at a temperature of 170-180°C for one hour. The rheological properties of the original and modified asphalt were determined by measuring properties such as penetration, softening point, ductility, penetration index, Marshall stability, and aging. The modified asphalt exhibited better rheological properties compared to the original asphalt, particularly in terms of stability and resistance to acid rain.
