Results of geotechnical and environmental laboratory tests on atmospheric fluidized bed combustion ash and stoker ash are presented. The testing program is directed toward assessing the adequacy of using these materials as structural fill in roadway embankment construction. Geotechnical tests include specific gravity, standard Proctor compaction, permeability, California bearing ratio, strength, and swell tests. Environmental tests include bulk chemical analysis of major and trace elements, toxicity characteristic leachate procedure, extraction procedure toxicity, and Indiana neutral water leachate tests. The fluidized bed combustion ash and mixtures with stoker ash exhibit significant cementitious strength increase, and swelling with time. The implications of test results relative to use as structural fill are discussed.
