My presentations Profile Feedback Log out. Before work commences, the installation company must prepare a preliminary laboratory study of the material to be stabilised containing the following information:. Variation of the natural water content w n: Demonstration of the use of decontaminated sediments in road construction Specific technical goals: 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.
About project SlidePlayer Terms of Service. If you wish to download it, please recommend it to your friends in any social system. Stabilization of sediments with lime 1. Apply the stabilising agent using a binder spreading machine equipped with a dosing system 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 cnf. It allows an estimate of the mixture density that can be achieved on construction sites and provides a reference parameter for assessing the density of the compacted layer of the mixture.
ini The stabilising agent 100066 either mixed into the ground soil using suitable equipment to correct the ground soil without removing and replacing it class A1-A2, and in all cases no lower than class A2-A4or into recycled material applied in layers according to design specifications minimum thickness 8 cm.
Executive design of demonstration road. Rammed Earth Is a technique for building walls using raw materials of earth and other martials such like clay. Definition of 1006 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.
Preliminary assessment of the optimum percentages of use of the treated sediments 1.
Determination of Proctor curve: Patrizia Rocchio Preliminary Results. Dredging, analysis and characterization of contaminated sediments 1 st step: Auth with social network: Mix the ground soil with the stabilising agent using equipment which scarifies, pulverises and mixes the material evenly.
The intensity of the colour depends on the humus content. Determination of CBR Index ratio used to characterise the bearing capacity of the mixtures, determined immediately after compaction and after a period of curing water 4. Nearly one-third or one-half of the total cost of construction. They cannot be used in the road constructions vnr they are water sensitive materials. Proctor curves Optimum water content.
Because of the great content of organic matter their usability thresholds will be assessed to demonstrate optimum stabilization with lime. Share buttons are a little bit lower. Extensometer system for measuring settlements at various depths in embankment layers.
Recycled material means inert material from demolition and maintenance work of buildings or infrastructures, including partial demolition and maintenance work.
