In this study, the possibility as ground improvement stabilizer obtained by admixing with clay and stabilizer due to calcium hydroxide for finely crushed waste melting slag is investigated. It is also examined environmental impact assessment of ground improvement stabilizer. From the test results, it is found that the required strength of subbase course obtained from unconfined compression test is satisfied under condition of more than cure duration 10days for the mixture soil (dry weight ratio 50%) of finely crushed waste melting slag and clay admixed on calcium hydroxide of 5%. The lead and cadmium values obtained from contaminant content and leaching concentration tests on finely crushed waste melting slag and the mixture soil can be satisfied for environmental quality standard, respectively.
