Abstract

Due to the increase of the amount of marine dredged sediments (MDS) and the cost of managing the disposal site is very high, a reutilization of dredged sediment is urgently needed in France. The primary goal of this research is to find a domain for reuse of MDS materials as a new material regarding the environmental issues, and other requirement needed. In this study, the MDS was used as replacement material in road construction. Hence, various tests need to be realized to identify if MDS could achieve the requirement needed in this domain. The secondary objective is to enhance the geotechnical characteristic and to reduce the pollution content of the MDS, by incorporating binders and sediments, and revealed the geotechnical characteristic. The geotechnical test result shows that the stabilization by hydraulics binders improve the geotechnical characteristic and could fulfil the requirement needed. The present of Fly Ash and Silica Fume in this study is aimed to reduce the pollution level, especially the heavy metal content. After the geotechnical study in laboratory results shows as expected then the study to identify the chemical characteristic was realized. In order to evaluate the environmental impacts, leaching test was performed. The Leaching test result shows that with 7% of Silica Fume and 10% of Fly Ash capable to fulfil the criteria needed, hence, the use of MDS is consider safe in term of geotechnical and environmental impact, as a new material in road construction
