The purpose of this paper is to design rationale for the use of protective pads of geotextiles and geomembranes permeability of PD using these pads. In order to justify the use of protective pads made of geotextile for reducing the defectiveness geomembrane soil fractions, the existing formulas to determine the thickness of the film element of impervious devices were examined. The calculations according to the formulas show that HDPE geomembrane with a minimum thickness of 1,0 mm, the protective lining of the geotextile should be applied at the average diameter fractions of soil of more than 6,5 mm, and for geomembranes HDPE - at a diameter of soil fractions of over 15,5 mm. In order to estimate the permeability of the TFG geomembrane using additional protective linings of geotextile in the scientific article the basic design schemes of such coatings with one and two layers of protective linings of geotextiles were considered. The evaluation results of water permeability of impervious surfaces with geotextile and for comparison - without geotextiles are given in a table. As it is shown by the data presented for the design scheme with a single layer of geotextile geomembrane at the base (in the presence of small holes in the geomembrane) the decrease the effectiveness of an anti-covering is more than 268,0 %, and for the settlement scheme covering with two layers of geotextile there will be a very large reduction in the efficiency, which almost completely reduces the effectiveness of the coating to the value of the geomembrane permeability of a soil layer without geomembrane with the filtration flow rate of 71,75 m
3/day, against water permeability of the geomembrane cover - 38,52 m
3/day. From the foregoing, it can be concluded that the application of a coating design of well filtering gaskets made of geotextile is justified in terms of protecting the geomembrane from mechanical damage, but greatly reduces the effectiveness of impervious cover in case of its damage.

The paper presents the results of the field study of the subsidence following the implementation of one of the road building methods. The field study was performed in the area alongside oil and gas field access roads built in the loose marshy ground (peat). The paper provides a description of the geosynthetics installation technology. Outdated road building technologies designated for weak road base conditions feature high consumption of materials and energy and substantial anthropogenic impact on the environment. These technologies comprise complete or partial replacement of the ground by sand, road metal, or macrofragmental material combined with timber as the reinforcing element of the base (a plank road). The objective of the field study was to develop an ecologically safe technology capable of reducing the anthropogenic impact on the environment and improving the strength and the operating safety of the road structure. The field study has proven that the aforementioned objective may be attained through the application of geosynthetic materials designated for the improvement of the bearing capacity of the weak road base. Geosynthetic materials and structures of the road subgrade ensure high speed of construction, high quality and reliability of the road structure, reduction in the consumption of materials and energy to assure the ecological safety of construction of oil and gas field access roads. Earlier, the author used the qualimetry method to assess the ecological safety. This method is used to assess the ecological safety in points. The assessments have proven that the reinforced base technology is preferable to the method of complete or partial replacement of the ground. Projection of the subsistence development pattern that makes it possible to evaluate the safety and the serviceability of the proposed solution is also an important efficiency factor. The field study involved a section of the oil and gas field access road outstretched along the oil transportation route that connected three Salym oil fields in Western Siberia.
