The major objectives of this study were to investigate the physical characteristics of selected refuse landfill waste soils which are excepted general waste materials and assessed the possibility of recycling for road construction or embankment materials. The old landfill site which is selected for this study is located at Youngyang in Kyungsangpukdo and it had been dumped and closed for 16-25 years. Therefore, the selected landfill waste soil became to geotechnical engineering characteristics when the closed landfill site is reused for road embankment materials. It was found that it would be better to use the selected waste soil mixed with the ordinary soil.

In this study, the dynamic compaction method was selected by analyzing field situation, soil condition data and compaction test characteristics of the special selected soils, and the compaction method for using the selected soils as the site restoration soil of the ${\bigcirc}{\bigcirc}$ city non-sanitary landfill maintenance project. The N value in the standard penetration test (SPT) before and after dynamic compaction increased by an average of 89% over the range 12~18, and the allowable bearing capacity of the plate bearing test (PBT) was ranged $150{\sim}227kN/m^2$, at least 80% higher than that before test. As a result, it can be seen that the same tendency as the dynamic compaction effect applied to the existing dredging and waste landfill is shown.
