Study on Influencing Factors of Asphalt Fume Releasing and its Hazards

A large number of experiments were done in order to find out the main factors which have an influence on the asphalt flue production in asphalt road construction and to master its dangers. The results show that the asphalt flue production varies with heating temperature, heating time, the asphalt thickness and stirring rate significantly. accordingly these are the main factors which influence the asphalt flue production. Further analysis by means of UV spectrophotometer and liquid chromatography shows that the asphalt flue contains serious harm to human body, such as aromatic compounds, alkanes, and sulfur heterocyclic compounds and other substances. therefore some steps should be taken to inhibit the production of asphalt flue for reducing the hazards to construction workers.
