Materials of cbr 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. Before work commences, the installation company must prepare a preliminary laboratory study of the material to be stabilised containing the following information:. 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 unu layer of the mixture.

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 lower.

It is an ancient building method. Because of the great content of organic matter their usability thresholds will be assessed to demonstrate optimum stabilization with lime. About project SlidePlayer Terms of Service.

Rammed Earth Is a technique for building walls using raw materials of earth and other martials such like clay. They cannot be used in the road constructions because they are water sensitive materials. Extensometer system for measuring settlements at various depths in embankment layers. Determination of Proctor curve: The stabilising agent is 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.
