E.Federal Highway AdministrationA survey was made of present municipal incineration practices in the United States and other countries. Previous world-wide research and development work on the use of incinerator residues as highway material is summarized. The types, quantities, and locations of municipal incinerator residues produced in this country were determined. The predominant factors affecting residue quality are the nature of the burning action and the degree of burn-out. Six basic types of incinerator residues were identified according to a classification system based on incinerator design. At the present time there are 141 incinerator plants and one pyrolysis plant in operation in 22 states plus the District of Columbia. Most of these plants are located in the northeastern states. These plants produce approximately 5.5 million tons of residue per year. Well burned out residue types 1 and 2 comprise 25 percent of the residue total. The incinerator residues available in the United States could supply from 1 to 9 percent of the annual highway aggregate requirements of the states in which the incinerators are located.80
