A comprehensive analysis of eight sets of samples of emissions originating from petroleum asphalt during the hot-mix process for preparation of asphalt paving mixes was carried out. Samples were collected on four days at two locations involving four asphalt cements of varying characteristics from three refineries. All gaseous substances, vapors and particulates which possibly could be associated with asphalt, including hydrocarbons, carbon monoxide, nitrogen dioxide, volatile sulfur compounds, ozone, aldehydes, phenols, metals and polynuclear aromatics, were identified using well recognized and accepted sampling techniques and analytical procedures. Based on test data of these analyses it was concluded that no significant air pollution or employee health problems can be expected or associated with the emissions from hot preparation of asphalt paving mixtures.
