| Description | The most commonly used process to produce asphalt paving mixtures involves mixing petroleum derived asphalt cements at elevated temperatures with mineral aggregates, such as sand, gravel, slag and various crushed rocks. In this manner approximately 350 million tons of paving mixtures are produced annually in about 4,500 hot-mix plants scattered throughout the country. When a hot asphalt paving mix is discharged from the mixing chamber, a bluish plume frequently arises from the mix. With the increasing concern about matters affecting the environment and the health and safety of workers, of the air including the emissions, in which measurements were made of the immediate vicinity of the pugmill during the hot mixing process. It was expected that the concentration of such emissions would be the highest at the pugmill, and this was the reason for selecting that area for sampling of emissions. The identification and determination of concentrations of all possible compounds that conceivably could be derived from the asphalt binder was the primary purpose of this investigation. A further purpose was to compare these findings with the emission standards or limits promulgated by the regulatory agencies. |
