Effects of a Fuel-Resistant Modifier on the High-Temperature Characteristics of Asphalt Binders

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