| ABSTRACT |
|
During expressway construction it has been input a lot of material, but it does not manage to estimate quantitatively. In this study, the total material requirement for construction of expressway, which separated direct material requirement and indirect material requirement each section was quantified by combining life cycle assessment (LCA) and material flow analysis (MFA). In the direct material requirement, sand 2.27E + 04 ton/km, limestone 1.02E + 04 ton/km and gravel 4.47E + 03 ton/km were required, in the indirect material requirement, gravel 2.75E + 04 ton/km, iron 9.80E + 03 ton/km and coal 9.74E + 03 ton/km were required. Material such as sand, limestone which has high direct material requirement is require of excess input prevention from construction site, and material such as iron, rare metals(chrome, nickel) and coal which has high indirect material requirement is require additional studies of resource management. |
