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.
Introduction Pavement design is the major component in the road construction. Auth with social network: S — Soil Mechanic.
Dredging sites individuation 2 nd step: The intensity of the colour depends on the humus content.
We think you have liked this presentation. Mix the ground soil with the stabilising agent using equipment which scarifies, pulverises and mixes the material evenly. It is an ancient building method. Determination of Cnd Index ratio used to characterise the bearing capacity of the mixtures, determined immediately after compaction and after a period of curing water 4. Dredging, analysis and characterization of contaminated sediments 1 st step: To improve the density and other properties of soil Increases the solid density improves strength Lowers its permeability Reduces.
Extensometer system for measuring settlements at various depths in embankment layers. My presentations Profile Feedback Log out. These samples belong to A group, that represents the highly plastic clay.

The installation surface must be prepared according to specification using laser-controlled equipment, and according to the specified apparent density NR B. Stabilization of the sediments with lime 2. To make this website work, we log user data and share it with processors.
Executive design of demonstration road Cross section and Materials Dredged sediments stabilized with lime 1. Published by Mariam Dye Modified over 4 years ago. Nearly one-third or one-half of the total cost of construction. Apply the stabilising agent using a binder spreading machine equipped with a dosing cn to guarantee even distribution of the stabiliser if the consistency and characteristics of the ground soil or the spreading speed vary.
Share buttons are a little bit lower. Patrizia Rocchio Preliminary Results. Variation of the natural water content w n: Preliminary assessment of the optimum percentages of use of xnr treated sediments 1.
