Calculation of road dust emissions before and after paving shows that paving is an effective measure for reducing road dust emissions in Kern County oil fields. Control efficiency values for particles smaller than 10 ..mu..m aerodynamic diameter averaged about 70 percent for paving with coldmix asphalt and 95 percent for paving with hot-mix asphalt. These control efficiencies are about the same for other particle size fractions up to 30 ..mu..m aerodynamic diameter. The higher efficiency associated with hot-mix asphalt reflects the substantially lower quantities of surface road dust found on hot-mix roads in comparison to cold-mix roads in Kern County. The emission reductions achievable by paving a given road depend on the VMT as well as the type of asphalt pavement used. VMT increases with increasing traffic count and length of the road segment. Emission reductions also depend on the texture (silt content) of the surface before paving and on the traffic characteristics, i.e., vehicle speed, vehicle weight and number of wheels per vehicle.
