Description
Summary:With a view of reducing the quantities to be landfilled, the Solvay Company has been working on the development of a treatment for polluted sediments: the Novosol® process. It allows fixing heavy metals and eliminating organic matter. This article reports on the characteristics of a treated sediment and on its use in road building techniques. From mechanical point of view, the performance of the mixtures incorporating sediments is satisfactory since their mechanical strengths are even higher than those of the reference mixtures. The leaching test carried out on the mixtures shows that the release is the same for both materials. Also, on the whole, these results suggest that using treated sediments in road building techniques is conceivable.
