Demonstration of the use of decontaminated sediments in road construction Specific technical goals: To make this website work, we log user data and share it with processors.

The installation surface must be cnd according to specification using laser-controlled equipment, and according to the specified apparent density NR B. About project SlidePlayer Unu of Service. They cannot be used in the road constructions because they are water sensitive materials. Materials of this group usually have high volume change between wet and dry states and they can be used only if stabilized in the construction of embankment, but cannot be used in construction of subgrade layers.

Patrizia Rocchio Preliminary Results.

Because of the great content of organic matter their usability thresholds will be assessed to demonstrate optimum stabilization with lime. Lime proportion requirement for soil stabilization 2.


Mix the ground soil with the stabilising agent using equipment which scarifies, pulverises and mixes the material evenly. Definition of the most appropriate mixture s of decontaminated dredged sediments and other standard materials The treated sediments will be applied in different proportions and percentages, in order to demonstrate the wide range of possible features and applications.
