Paved roads constitute a major category of PM-10 and PM-2.5 emissions in urban areas. Paved roadway resuspension processes emit antiskid materials, abraded pavement particles, rubber tire fragments, and dirt that is tracked from paved areas. This report presents the results of research, sponsored by the Colorado Department of Transportation, to (1) determine the relationships between the paved roadway surface dust characteristics and fine particle emissions, and (2) evaluate emission control measures that reduce road surface silt loadings (either by preventive or mitigative means). Several types of field were used in performing this research. The Correlation Studies entailed simultaneous paved road plume profiling and road surface material sampling at three test sites in the Denver metropolitan area. The composition of collected airborne and surface samples were analyzed by chemical and microscopical analysis. The upwind/downwind airborne particulate matter samples that were selected for analysis included PM-10 and PM-1.5, while the road surface samples included the resuspended PM-10 and PM-2.5 from MRI's Dustiness Test Chamber. Additional composite surface sampling of Denver arterial roadways compared the effects of winter sanding and alternative chemical deicers on surface loadings.
