چکیده انگلیسی:
The objective of this paper is to characterize the elemental composition, chemical compounds, oxidative
aging and the compatibility of bio-asphalt modified with bio-oil. A petroleum asphalt was modified with
treated and untreated bio-oil at 2%, 5% and 10% by weight to prepare bio-asphalt, respectively. Gas
chromatographyemass spectrometry (GC-MS) was employed to characterize the chemical compounds in
the bio-oil. The Fourier Transform Infrared Spectroscopy (FTIR) was utilized to explore the influence of
bio-oil on the aging performance of asphalt. The compatibility of bio-oil with petroleum asphalt was
investigated using automated flocculation titrimetry (AFT) based on flocculation stability. The elemental
composition analysis revealed a higher amount of oxygen in the bio-oil. The GC-MS results showed the
presence of chemical compounds with low boiling temperatures, which have potential environmental
impacts and health concerns if used in hot mix asphalt. The FTIR results indicated the presence of aromatic and nitrogenous compounds, alcohols, ethers, ketones, carboxylic acids, aldehydes, esters, acyls,
alkanes, polymeric OeH, NH2 and water. The AFT results implied a stable and compatible mixture of 2%
bio-asphalt. The study also suggested that with an increase in the fraction of bio-oil, the compatibility
with petroleum asphalt would decrease.
