Abstract
The enhancement of asphalt properties was investigated through utilizing the Buton rock asphalt (BRA) and styrene–butadiene–styrene (SBS) in this study. Despite of the splendid high-temperature resistance of the BRA-modified asphalt, it could be liable to low-temperature cracking. Hence, a composite BRA/SBS-modified asphalt was explored. The rheological tests, Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC) were employed for analyzing the rheological, thermal, and chemical stability properties of the samples. The findings demonstrated that SBS promoted the low-temperature crack resistance of the BRA-modified asphalt, and BRA improved the thermal stability and thermal oxygen aging resistance of the SBS-modified asphalt. Considering the overall anti-aging and anti-fatigue effectiveness, 2 % SBS and 10 % BRA were proposed as the appropriate dosages for the modified asphalt. The analysis of correlation revealed that the BRA could be introduced to mitigate the influence of aging on the performance of SBS-modified asphalt to resist the irreversible deformation. This study could address the limitations of the BRA-modified asphalt and promote its application in road constructions.
