On August 12-13, 1997, researchers from the National Institute for Occupancy Safety and Health (NIOSH) evaluated prototype engineering controls designed for the control of fugitive asphalt emissions during asphalt paving. The Dynapac engineering control evaluation was completed as a supplement to an existing Department of Transportation (DOD) project to evaluate the effectiveness of engineering controls on asphalt paving equipment. NIOSH researchers are conducting the research through an interagency agreement with DOT's Federal Highway Administration (FHWA). The National Asphalt Pavement Association continues to play a critical role in coordinating the paving manufacturers' and paving contractors' voluntary participation in the study. The study protocol for the original FHWA project included two major phases. During the primary phase, NIOSH researchers visited each participating manufacturer and evaluated their engineering control designs under managed environmental conditions. The indoor evaluation incorporated tracer gas analysis techniques to quantify the control's exhaust volume and to determine the capture efficiency.
