EXPOSURE OF PAVING WORKERS TO ASPHALT EMISSIONS (WHEN USING ASPHALT-RUBBER MIXES)

In response to possible concerns in regard to worker exposure to airborne contaminants from Asphalt-Rubber products, Dan Napier and Associates conducted a study to evaluate the exposure of paving crew and blender crew workers to volatile organics, benzene, benzene soluble organic, coal tar pitch volatiles and specific polynuclear aromatic hydrocarbons. The study was commissioned by Manhole Adjusting Contractors Inc. on behalf of the Asphalt Rubber Producers Group. The study sought to identify any occupational exposures inherent in the paving procedures and to compare asphalt fume exposures with asphalt-rubber mixes to exposures connected with the use of conventional asphalt mixes and to Permissible Exposure Limits (PELs). Monitoring was conducted over a period of two and one-half years. Sampling was performed to obtain a representative overview of the different processes used by Manhole Adjusting Contractors Inc. Time periods between sampling were set up to allow review of the results and procedures and to make any necessary changes in either sampling procedure or analytical technique. Personal sampling equipment was used and emphasis was placed on monitoring workers in direct contact with the asphalt fumes. The results of the data interpretation clearly demonstrated that the risks associated with the use of Asphalt-Rubber products was negligible. Emission exposures in Asphalt-Rubber operations did not differ from those of conventional asphalt operations.
