Abstract

This study explored the compacition characteristics of organic weathered soils. Weathered soils were collected around the Gwangju University in Jinwol-dong, Gwangju city, and coal was used as organic material. Weathered soils were mixed with coal so that the ratio of organic elements against mixed soil can be 0%, 25%, 50%, and 75% respectively. Compaction tests were carried out on these organic mixture soils in different ratios of organic materials. And soap water instead of water in compaction tests was used. Through this study, We knew that the bigger the organic material ratio was, the more the optimum moisture content increased and the less the maximum dry unit weight reduced. In case of using small compaction energy, using soap water instead of water improved the compaction efficiency a little.
