Health Hazard Evaluation Report: HETA 2001-0536-2864, Crumb-Rubber Modified Asphalt Paving: Occupational Exposures and Acute Health Effects
In 1991, Congress enacted the Intermodal Surface Transportation Efficiency Act (ISTEA), which required each state to use a minimum quantity of 'crumb-rubber modified' (CRM) hot-mix asphalt (HMA) paving material. Because of industry and labor concerns over the lack of available information on the environmental and human health effects resulting from the use of CRM-HMA, along with the higher initial cost of using this paving material, a temporary legislative moratorium was passed and the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation, Federal Highway Administration (FHWA) were directed by Congress to evaluate the potential environmental and human health effects associated with the use of CRM asphalt. The National Highway System Designation Act of 1995 eliminated the mandate requiring the use of CRM asphalt but continued to require research concerning CRM asphalt paving. In June 1994, the National Institute for Occupational Safety and Health (NIOSH) entered into an Interagency Agreement with the FHWA to evaluate occupational exposures among asphalt road workers. A study protocol developed by NIOSH included the following objectives: (1) Develop and field test new methods to assess asphalt fume exposures; (2) Characterize and compare occupational exposures to CRM asphalt and conventional (CONV) asphalt; (3) Evaluate potential health effects associated with CRM asphalt and CONV asphalt.
