The report gives results of a short-term in-house project to characterize emissions from a simulated asphalt roofing kettle, performed at EPA/AEERL. Hot asphalt surfacing and resurfacing has been identified as a possible significant source of volatile organic compound (VOC) emissions that may affect human health and contribute to the ozone non-attainment problem. The purpose of the study was to collect, identify, and semi-quantitate as many compounds as possible that are discharged during the open heating of roofing asphalt and relate them to the amount volatilized into the air. Types 1, 2, and 3 mopping grade asphalts were chosen for the study. They constitute more than 90% of roofing asphalt used. Samples of each type of asphalt were placed in a simulated roofing kettle, heated to predetermined temperatures, and sampled for volatile and semi-volatile organic emissions. Compounds identified during the study were alkanes, aromatics, a ketone, and an aldehyde.
