Technology for Use of Incinerator Residue as Highway Material.

摘要

Incineration of solid waste is a major means of refuse disposal in many major metropolitan areas. The residues are a heterogeneous mixture of components such as glass,metals,ceramics,ash,and combustibles. Six basic types of incinerator residues were identified in this study. Representative samples of these materials were obtained in the field and subjected to extensive laboratory study. The materials were characterized and evaluated for performance in base course and wearing surface mixtures. Based on these tests,incinerator residue is not recommended for use in portland cement concrete. It is,however,recommended as an aggregate in bituminous mixtures. Three experimental sections were placed using incinerator residue in bituminous wearing surface mixtures. The mixes used have performed well since their placement in the latter part of 1975. Early data on skid resistance for these mixtures indicates that the addition of incinerator residue does improve pavement skid resistance.
