Bitumens, like coal-derived tars and pitches, as well as petroleum asphalts, have been widely used in many branches of industry and economy. A dramatic limitation of the application areas for bitumens of coal origin is currently observed, due to the carcinogenic action of some bitumen-containing polycyclic aromatic hydrocarbons, especially benzo(a)pyrene (BAP). This hazardous condition was the reason for shutting down plants involved in the coking of coal-tar pitch in Poland and Germany. As a result, many research studies on decreasing BAP content in bitumen materials have been performed.
