For the sake of safe disposal and re-utilization of incineration bottom ash of municipal solid wastes, two kinds of incineration bottom ash, which were from typical grate incinerator and fluidized bed incinerator respectively, were tested in laboratory. According to the grading character, compaction, shearing strength and compression property, engineering properties of the two incineration bottom ash were analyzed and compared. Also, the properties were compared with data from other areas, which may offer a reference to incineration bottom ash&s utilization as road bed fill.
