Timely application of GIS technologies is determined by the need to create an intelligent digital control system for spatial surveying and road data in combination with information resources about the real state of infrastructure facilities. It is necessary to use the techniques of data collection, processing, and analysis corresponding in accuracy, reliability, and efficiency, such as the tasks set for the GIS, as well as modern capabilities of computer technology and software. The current lack of the concept and methods of geoinformational support for the functioning of the transport infrastructure of cities in technogenic-deformed territories (TDT) makes the solution of this issue relevant. Today, it is technically feasible to create a space-time model of deformation processes based on data from many years of field studies also using methods of mathematical modeling of mining processes and surveying calculations. The main method of research is the analysis of field studies using GIS modeling, using mathematical and statistical methods. The source data are published materials of long surveying and geodetic observations and statistical materials created in previous years by various organizations of Ukraine.

Dependence is considered between the size of relative diametral gap and descriptions of work of the motor-axial bearing on the different rates of movement of diesel engine: by the type of the mode of greasing, thickness lubricating layer, by the coefficient of friction and intensity of wear.

Defining the elastic modulus of bulk materials is an important issue in quality assurance of design and construction of motorway bases. The analysis of current regulatory framework shows that there are no applicable methods for defining the elastic modulus of loose (bulk) materials in laboratory conditions. Moreover, if new or underinvestigated materials are used for motorway bases, it is necessary either to abandon their use or define their compliance with the regulations after motorway base construction. In view of the latter, an experimental technique and a device for defining the elastic modulus of bulk materials in laboratory conditions are developed. Following this technique, the elastic modulus of 5 mm – 20 mm, 20 mm – 40 mm crushed dump blast furnace and steelmaking slags was defined. Comparison of the obtained results with the recommended design values of the elastic modulus of similar materials shows good convergence (the difference is within 8%). There is no connection between the diameter of a stamp transmitting load to a sample and the specified value of the elastic modulus. Deviations do not exceed 10% for ∅50 mm, ∅120 mm, ∅150 mm stamps.
