As a result of the research and calculations we can draw the following conclusions:
Construction of roads in the areas of occurrence of saline soils - a complex multidimensional problem, which
includes the study of soil properties and conditions of their education, taking into account the specifics of the road
constructions and features of the technology of production of excavation. The complexity of construction on saline
soils due to the fact that the deformations are manifested both during erection of structures, and in their operation
period. The grounds on saline soils is necessary to design and arrange tailored to the specific properties of the latter,
which are responsible for the development of excessive deformation and decrease in strength of the soil in their
desalination.
Nowadays, into construction practice quite successfully begins to implement technology, in which the weak base
of the road mound reinforced by so-called flexible ground piles (geo pile), i.e. sand drains for flexible shells of
geosynthetics, working as a high-pile vertical drains.
Improving strength and deformation characteristics of soil compaction in the area increases the bearing capacity
of the soil, which allows to pass on the modified base ground heavy loads. Filled draining soil piles simultaneously
function as vertical drains and ensure acceleration of the process of consolidation of saturated soils by reducing the
way of water filtration, squeeze from the weak strata.
