The object of this work was to investigate the use of incinerator residue as an aggregate replacement material in a bituminous concrete wearing course.
Five types of incinerator residue were investigated in the laboratory in the production of asphaltic concrete specimens. The residues ranged from a poorly burned material to a well-burned material. Some experimentation was performed using a 100 percent substitution; however, this did not produce acceptable asphalt concrete. The reported work used a 50 percent substitution rate with conventional Pennsylvania limestone. All mixes were designed to conform to the Pennsylvania ID-2 wearing course gradation and were laboratory tested using the Marshall method of mix design. Satisfactory laboratory mixes were identified for the well-burned incinerator residue. After completion of the laboratory research and design, three experimental pavements were designed, constructed, and monitored.
