||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. Although 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. Volatile organic compound (VOC) analyses showed significant amounts of benzene emitted from both types of asphalt studied. An analysis targeting 16 polycyclic aromatic hydrocarbon (PAH) species of primary interest revealed significant emissions of 7 of the 16 species when the AC10 aspalt without rubber tests were compared to the facility blank tests. The emissions of 5 of 16 PAH species were significantly higher in the AC10 thin layer with rubber tests than in the facility blank tests. The concentrations observed, though significant, were close to the limit of detection.
