About project SlidePlayer Terms of Service. Determination of Proctor curve 2. 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 unni the wide range of possible features and applications.

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. Demonstration of the use of decontaminated sediments in road construction Specific technical goals: Determination of Proctor curve: They cannot be used in the road constructions because they are water sensitive materials.
