The paper proposes an impregnation composition for cement concrete roads used as an ice-phobic coating. The composition has been made based on keratin-containing components derived from animal waste with the addition of water-soluble polymers. The main parameter of serviceability of the coating impregnated with the developed composition was assessing the adhesion resistance of ice crust to concrete under the influence of mechanical loads. For this purpose, tests of big specimens (surface area 1925 cm2) in laboratory conditions with application of vibration and impact loads and modelling of thermal stresses were conducted. The test results showed the effectiveness of the ice-coating, as in all experiments, the uncoated specimens showed a greater resistance of the ice crust to mechanical stresses. An additional evaluation parameter was comparing the water absorption capacity of coated and uncoated concrete. The test results showed a significant difference in the water absorption capacity of the uncoated specimens, exceeding the coated specimens by 47%. Due to the results obtained, it will be possible to use the impregnation compound effectively to improve the ice resistance of cement concrete coatings.

The current calculating theories of massive constructions are based on the simplified models without consideration of factors settlement as nonhomogeneous environments interaction, the interacting environments nonlinearity or considering them separately and conditionally. Therefore, equivalent numerical model designing of bored piles interaction with the soil mass and designing of a nonlinear technique of numerical calculation of similar systems on its basis is a modern and relevant task, which is an effective tool for a number of relevant geotechnical tasks solutions. The calculation of reinforced concrete bored pile with the real diagrams of a pile material deformation and surrounding rock massif has been presented in the article. The computer program allows receiving the strain-stress state of a pile and the surrounded massif as one heterogeneous body. New calculation approaches of the reinforced concrete bored pile can be used in the standards modernization when transferring from the regulatory framework of Kazakhstan to Euro code according to the reform concept.
