EVALUATION OF EMISSION FROM PAVING ASPHALTS
Lutes, C., R. Thomas, AND R. Burnette. EVALUATION OF EMISSION FROM PAVING ASPHALTS. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-94/135.
The report provides data from pilot-scale measurements of the emissions of specific air pollutants from paving asphalt both with and without recycled crumb rubber additives. he methods used in this work measured emissions from a static layer of asphalt maintained for several hours near the highest temperature likely to be encountered in a "real" paving operation (176 C). lthough concentration levels observed for most species were in most cases near the detection limits of the analytical methods applied, statistically significant emissions of a variety of pollutant species were observed. olatile organic compound (VOC) analyses showed significant amounts of benzene emitted from both types of asphalt studied. n analysis targeting 16 polycyclic aromatic hydrocarbon (PAH) species of primary interest revealed significant emissions of 7 of the 16 species when the AC10 asphalt without rubber tests were compared to the facility blank tests. he emissions of 5 of 16 PAH species were significantly higher in the AC10 thin layer with rubber tests than in the facility blank tests. he concentrations observed, though significant, were close to the limit of detection. tatistically significant emissions of both total particulates and PM10 were found from both types of asphalt hot-mix material tested.
