Summary: 

In this study of the potential of using dredged marine sediments in road construction, the first objective is to determine the physical and mechanical characteristics of fine sediments dredged from a harbour in the north of France. The impacts of these materials on the environment are also explored. In the second stage, the characteristics of the fine sediment are enhanced for use as a road material.

Conclusion: 
In this study, the amount of binders added to the proposed mixes is comparable to the amount used in standard materials. These results make the designed mixes economically viable. In terms of environmental impacts, the values of chlorides and the soluble fraction classify the mix with lime as non-dangerous material. According to French legislation of MSWI bottom ash this mix can be used as road material. On the basis of these results, the proposed methodology could constitute a starting point for the investigation of possible beneficial uses of polluted sediments in the field of road construction.
