Abstract
On November 4-7, 1996, researchers from the National Institute for Occupational Safety and Health (NIOSH) evaluated a first-generation engineering control designed to capture and remove fugitive asphalt emissions during asphalt paving. The Roadtec engineering control evaluation was completed as part of a Department of Transportation (DOT) project to evaluate the effectiveness of engineering controls on asphalt paving equipment. The scope of this report is limited to the Roadtec phase two (field) evaluation of a single engineering control installed on a Roadtec Model RP 180-10 asphalt paving machine. The tested design consisted of twin exhaust hoods mounted above the auger area, one on each side of the auger gear box. Each hood incorporated flanges on the leading and trailing edges of the hood, to enclose approximately 70 percent of the top of the auger area. Airborne contaminants were exhausted from the auger area through the use of two hydraulic exhaust fans.
