<p>An asphaltic pavement course composition is disclosed, as well as process for making same. The composition utilizes, as the major ingredient, the residue from a refuse incinerator, which residue contains less than 6%, preferably less than 2%, by weight of ferrous material. The low-ferrous content residue is combined in an asphaltic road base course composition or other asphaltic pavement course composition also containing asphalt and mineral aggregates, to produce a pavement course material with excellent physical properties at low cost. Incinerator residues are a major source of environmental pollution, requiring the use of sanitary landfills to dispose of same, and the present invention reduces or even obviates the need of such landfills.</p> |
