The lightweight bubble mixture soil is used for soft ground rear-filling material by applying reduced weight on structure. However, comparing with the general soil, it is not applied in domestic because of initial phase cost of construction. General soil, which has lower initial phase cost is usually used for rear-filling, but the use of overlay method of general soil is reduced as the number of layers increases. Especially box structure placed in soft ground or the overlay method when gap near pier rear-filling can be replaced with temporary alternative method, however, it can't be a solution to gap by generation of extra weight of thickness of overlaying. Therefore, execute LCC analysis of two alternative-the general and the lightweight bubble mixture soils, which are rear-filling material of box structure- and present economical analysis in order to make resonable decision from the economics. As a result, although the lightweight bubble mixture soil takes higher initial phase cost than the general soil, it has been analyzed to procure economical efficiency by having less cost of maintenance.
