摘要
Abstract
To investigate the influence and underlying mechanisms of rice-husk-derived bio-oil on the high-temperature performance of petroleum asphalt binders,bio-asphalt samples were produced by incorporating the bio-oil in-to six commonly used base asphalts.Fundamental binder properties were evaluated through standard asphalt characterization tests,whereas high-temperature rheological behavior and substitution performance were ex-amined using dynamic shear rheometry,rotational viscosity measurements,and SARA compositional analy-sis.The results demonstrate that the incorporation of rice-husk bio-oil increases penetration and ductility while decreasing the softening point of all six base binders.The bio-oil also leads to reductions in the complex shear modulus(G*)and rutting parameter(G*/sinδ),accompanied by an increase in the phase angle(δ),yet does not alter the high-temperature classification.The rotational viscosity of six kinds of bio-asphalt is lower than that of the corresponding petroleum asphalt.关键词
