摘要：

Replacement of commercial carbon black by carbon blacks obtained from tyre pyrolysis (CBp) would be an interesting commercial application for CBp. Recent work showed that CBp improves the rheological properties of bitumen. This improvement is most probably due to interaction between CBp and asphaltenes, the most polar and heaviest bitumen components. In the present work asphaltenes from commercial and pyrolytic bitumen and a CBp-bitumen mixture were analysed by ESCA, SIMS and i.r. spectroscopy. It was found that the CBp surface is covered with a non-extractable layer of bitumen compounds, especially with aromatic compounds without or with a small concentration of alkyl groups. Asphaltenes from pyrolytic oil have fewer alkyl groups than asphaltenes from commercial oil. Therefore pyrolytic bitumen reinforced with CBp should be an attractive material for road construction.
