摘要：To effectively evaluate the high-temperature characteristics of a fuel-resistant modified asphalt (FRMA), five different types of asphalt were selected, and a fuel-resistant modifier (FRM) was added to the asphalt to prepare five kinds of FRMA, and the fuel resistance of the 10 above-mentioned asphalt samples was then evaluated. Moreover, the high-temperature performance of different asphalt samples was explored, the influences of the FRM on the penetration, softening point, and rheological indexes of the different asphalt samples were analyzed. A Pearson correlation analysis was conducted on the different high-temperature indexes. Based on the results, compared with the original asphalt, the fuel resistance of the FRMA was improved by about 22% on average; the FRM was able to reduce the penetration, phase angle, and non-recoverable creep compliance of the asphalt; increase the softening point, complex modulus, rutting factors, and creep recovery; and effectively improve the high-temperature performance of the asphalt. However, as the temperature increased, the effect of the FRM on the improvement of the high-temperature performance of the asphalt declined. In addition, compared with the base asphalt, the FRM exerted a more significant effect on the rheological properties of the modified asphalt. According to the Pearson correlation analysis of the high-temperature indexes, apart from penetration, the softening point and rheological indexes featured excellent accuracy and applicability in the evaluation of the high-temperature performance of FRMAs.
