NIOSH 1996 Dec; :1-49
This report presented the findings from a field survey conducted near Jasper, Indiana, during asphalt pavement construction (SIC- 1611) along Interstate 64 in southern Indiana, as part of a larger study of asphalt paving. Koester Equipment Company applied 2,370 metric tons of crumb rubber modified (CRM) asphalt and 3,670 metric tons of conventional asphalt. The study indicated that asphalt fumes and other exposures were below current limits. The conventional asphalt formula contained 23% recycled asphalt pavement. Higher concentrations of total particulates, respirable particulate, benzene soluble particulate fraction (BSF), polycyclic aromatic compounds (PACs) and other sulfur containing compounds were noted over the screed during the CRM asphalt paving periods than during conventional asphalt paving periods. Benzothiazole (95169) was detected only during CRM asphalt paving periods. Acute symptoms reported by workers were associated with asphalt paving exposures, and higher symptom prevalences were associated with CRM asphalt paving. The extent to which the exposure and health findings may have been influenced by the presence of recycled asphalt pavement was not known.
