Purpose: The main aim of this study is to investigate the potential reuse of dredged material for road construction purpose. Theory and Methods: In this study, the laboratory tests were performed on raw sediment and sediment mixed with different percentage of lime and cement content to assess the impact of lime/cement treatment on the engineering properties of dredged material and suitability of dredged material for road construction purposes. Atterberg limit tests, miniature compaction test and unconfined compression test was performed on raw and lime/cement treated dredged material. The samples were cured for 1 day,7 and 28 days for unconfined compression test. Results: The test results show that the plastic limit of treated samples increases with addition lime/cement when their plasticity index decreased. The unconfined compressive strengths of the mixtures showed significant increases depending on the increasing additive content and curing time. The maximum 7-day unconfined compressive strength values were achieved by 4% lime 15% cement content. Conclusion: The optimum binder contents are 4% an %15 of the dry weight of dredged material for lime and cement, respectively. As shown in the experiments, the engineering properties of dredged material can be improved by using additives and reused as subbase layer of road.
