X-ray photoelectron spectroscopy(XPS),gel chromatograph,()~1H-NMR,and electrolytic(titration) technique were employed to identify various types of sulfur-containing compounds and to determine their contents in sulfured asphalt.The sulfidation mechanism was discussed.The results show that the main products of asphalt sulfidation are disulfides and sulfoxides,and sulfur is mainly substituted for the β-hydrogen in asphalt during the sulfidation.
