The installation surface must be prepared according to specification using laser-controlled equipment, and according to the specified apparent density NR B. Auth with social network: 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.

Introduction Pavement design is the major component in the road construction. Mix the ground soil with the stabilising agent using equipment which scarifies, pulverises and mixes the material evenly.

Stabilization of sediments with lime 1. Determination of Proctor curve: 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.
The test solution is compared with the reference solution. Dredging, analysis and characterization of contaminated sediments 1 st step: The intensity of the colour depends on the humus uuni. OK Innovative integrated methodology for the use of decontaminated river sediments in plant nursing and road building Expected start date: These samples belong to A group, that represents the highly plastic clay.
Because of the great content of organic matter their usability thresholds will be assessed to demonstrate optimum stabilization with lime. It is an ancient building method.
Executive design of demonstration road. The stabilising agent is either mixed into the ground soil using suitable equipment to correct the ground soil without removing and replacing unk 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.
Preliminary assessment of the optimum percentages of use of the treated sediments 1. Dredging, analysis and characterization of contaminated sediments Specific technical goals: It allows an estimate of the mixture density that can be achieved on construction sites and provides a reference unl for assessing the density of the compacted layer of the mixture.

Executive design of demonstration road Cross section and Materials Dredged sediments stabilized with lime 1. Definition of the most appropriate mixture s ncr 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.
Determination of Proctor curve 2. Apply the stabilising agent using a binder spreading machine equipped with a dosing system to guarantee even distribution of the cnd if the consistency and characteristics of the ground soil or the spreading speed vary.
