This report summarizes data on air emissions from the asphalt hot mix industry. A representative asphalt hot mix plant was defined, based on the results of an industrial survey, to assess the severity of emissions from this industry. Source severity was defined as the ratio of the maximum time-averaged ground level concentration of an emission to the primary ambient air quality standard for criteria pollutants or to a modified threshold limit value for noncriteria pollutants. For a representative plant, source severities for particulate, nitrogen oxides, sulfur oxides, hydrocarbons, and carbon monoxide are 4.02, 1.83, 0.67, 0.96, and 0.01, respectively. Source severities for POM's and aldehydes are 0.14 and 0.13, respectively. The report describes the manufacture of asphalt hot mix, emissions produced, sources of emissions, the growth and nature of the industry and the status of pollution control technology.
