Currently, in the case of Korea"s coal mines, due to large amounts of pyrite(FeS₂), marcasite(FeS), etc in minerals, an AMD(Acid Mine Drainage) is being formed. If the AMD was to be oxidized and neutralized through physical·chemical, natural purification processes, a by-product coking property and a deposit of light yellowish red sludge come about. Currently, most of the sludge from processing AMD are reclaimed or some are used as a secondary material for cement. Road pavements up until now were considered that preventing water infiltration and not reducing the support of the road were the best measures to enhance durability and therefore in most cases, cement concrete pavement or asphalt pavement are applied. However, these pavements involves various problems such as microorganisms not being able to live underground and the desertification of soil. One of the countermeasures proposed to remedy these problems is soil-cement pavement which is a environmental-friendly road pavement method. In this research, mine sludge which is environmentally safe, has low organic matters, and has a soil-like yellowish red color, is planned to be used as an admixture of soil-cement pavement, and the research conducted was of evaluating the proper compressive strength, durability test, and environmental threats using synthetic fiber as a countermeasure to solve fissure from long-term lack of durability and winter-time freezing/thawing due to previous soil-cement pavement problems. As a result, the most suitable mixture Case 4(exhausted mine sludge 5wt%, synthetic fiber 0.5wt%, fiber length of 20mm) which satisfies the domestic soil-cement pavement standards of compressive strength of 30kg/cm² and above and weight loss of 14% and lower after freezing/thawing test was deducted.
