The results are presented of the engineering properties of incinerator residues and the potential use of the residues in geotechnical applications. Physical and chemical properties of incinerator residue, as well as its geotechnical properties are reviewed. Soil stabilization using fly ash is described, as well as many potential applications of refuse incinerator residues. The study showed that both washed clinker and fly ash have the prerequisite properties for use in geotechnical applications. Both materials exhibit high strength and are relatively free-draining, typical of granular materials. Their lower compacted densities relative to conventional earthfill are advantageous when used as fill or in embankments constructed over soft, compressible ground, since this would result in smaller foundation settlements. The pozzolanic or hardening properties of the fly ash were also evaluated to assess the potential usage of the fly ash as an admixture in the stabilization of soft soils.
