Abstract

This study was carried out to investigate the geotechnical characteristics and field application of soil mixed with waste lime. Waste lime used in this study is producted as a by-product in the manufacturing process of making Na$_2$CO$_3$from local chemical factory in Incheon. Currently about 320 milton tons of waste lime are accumulated and annually 100,000 tons are producted. In this study, feasible use of waste lime mixed with granited whathered soil, clay, crushed rock was invesigated through laboratory tests including specific gravity test, sieve analysis, hydrometer analysis, compaction test, CBR test. Field investigations were conducted on the road construction site in Incheon.
