Bitumen and the bitumen part of asphalt are analysed mainly by GC-MS method. The content of polynuclear aromatic hydrocarbons (PAHs) is 0.2 % of the bitumen part of asphalt. This amount decreases in old manufactured asphalt. Some quantitative data about the heating of asphalt in air reveals the formation of large amounts of asphaltene during the asphalt preparation immediately before the application, and of some oxidised derivatives of PAHs. By considering the extension of surfaces covered by bitumen derivatives, the authors pose the question of whether the PAHs of bitumen are really dangerous for asphalt workers and for citizens.

Abstract
Bitumen and the bitumen part of asphalt are analysed mainly by GC-MS method. The content of polynuclear aromatic hydrocarbons (PAHs) is 0.2 % of the bitumen part of asphalt. This amount decreases in old manufactured asphalt. Some quantitative data about the heating of asphalt in air reveals the formation of large amounts of asphaltene during the asphalt preparation immediately before the application, and of some oxidised derivatives of PAHs. By considering the extension of surfaces covered by bitumen derivatives, the authors pose the question of whether the PAHs of bitumen are really dangerous for asphalt workers and for citizens.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
