impact on the environment. Generally, these sediments may be a dip or a land storage for the
most polluted. However, these solutions are facing a regulatory increasingly rigid in terms of
environmental protection. Faced with this problem, new alternative ways of management are
required,
such
as
road
construction.
This study is carried to make a characterization of entry pass’s sediments for enhancement in the
shape layer, this step is carried out through a series of physical and mechanical tests. The results
of various geotechnical tests have deduced using the GTR classification that sediments of the
entrance channel of the alluvial materials are insensitive to water resistant and present lowly
compressibility and friability due to the fineness of the grains, their use shaped layer requires
taking certain measures such as treatment, irrigation and surface protection.
Keywords: dredging, sediments, physical behavior, mechanical behavior, GTR classification,
the shape layer, valorization.
