Abstract

To evaluate the effect of thermal oxidative aging on the performance of rubber powder-modified bio-asphalt, this paper adopted rheological evaluation indicators to analyze the high-temperature deformation resistance of bio-asphalt and rubber powder-modified bio-asphalt. Based on the rheological evaluation indicators, an aging kinetic model of rubber powder-modified bio-asphalt was built at different aging temperatures and times. The results show that the anti-aging ability of rubber powder-modified bio-asphalt is significantly better than that of bio-asphalt, and the larger rubber particles lead to stronger anti-aging ability. As the aging time is extended, the high-temperature deformation resistance of rubber powder-modified bio-asphalt increases non-monotonically. On this basis, aging kinetic equations were established based on three rheological indicators, including the rut factor, relative difference in the strain recovery rate, and relative difference in unrecoverable creep compliance. The aging kinetic model built by rut factor fitting shows the best correlation between the calculated values and experimental measurement values, which can reflect the actual aging process of rubber powder-modified bio-asphalt and quickly evaluate its viscoelastic properties.
