Abstract: This paper introduces a cost effective and environmental friendly in-situ solidification of soft mucky cohesive soil technique that replacing the conventional soil improvement method of removal and replacement for a highway project in an alluvial plain with well-developed rivers and creeks and hidden historical waterways. The construction techniques of the in-situ soft mucky cohesive soil are also briefly introduced and a case history of the project that applying this soil improvement method is presented in this paper. Further, the applicability as well as results of using this technique for strengthening of shallow deposited soft cohesive soils are evaluated.

Key words: Soil Improvements; , In-situ Solidification, Highway Subgrades, Energy Saving and Environmental Protection
