Abstract The government and academic circle have concentrated their efforts in recycling the waste construction material, which are relatively easy to reuse, but it's been limited to recyclable aggregates from waste concrete, asphalt concrete and bricks. The amount of waste construction material reaches 129,572 ton/day, which accounts for 50% of the total wastes nationwide. And the soil among the construction waste is 6,657 ton/day or 5.1%. Though many of them are reused for neighboring construction sites, contaminated soil amounting to 1,843ton/day equivalent to 27% is buried at the designated landfill. The sources of such contaminated oil include gas station or oil storage, when the underground structure of those facilities was demolished. It's substantially difficult to identify the sources of contaminated soil since the construction sites are closed to outside. The contaminated residual soil is usually used for backfill. Since it's been broadly used irrespective of the region and use it's necessary to come up with the measures to deal with the contamination of residual soil from the early stage of the project. The study, for recycling the oil-contaminated soil, was intended to evaluate and analyze the decontamination character, depending on heating temperature and detention time, and review the c
