PROBLEMS AND WAYS OF SOLVING THE ISSUES OF OPERATING DURABILITY OF TECHNICAL MEANS OF TRAFFIC CONTROL

Abstract

Introduction. The efficiency of road transport functioning greatly depends on the technical level and condition of roads. Modern roads must ensure traffic safety. Also, it has to be considered that the transport and operational level of a modern road is determined not only by the combination of geometric elements of the route, the number of traffic lanes, the condition of the roadway and roadsides, but also the engineering equipment of the road. Mostly, traffic safety requirements are met dut to a wide and skillful use of engineering equipment. Modern standards include, among other things, technical means of traffic control of the roads. Problem statement. The impact of various factors on the durability of polymeric materials Purpose. Solving the issues of operational durability of technical means of traffic control. Materials and methods. Theoretical and empirical methods of scientific researches are used to analyze the impact of various factors on the durability of polymeric materials. Results. The analysis of foreign researches concerning the impact of various factors, and especially ultraviolet radiation on durability of polymeric materials is performed. Conclusions. When conducting tests on artificial aging in order to predict changes in the properties of polymeric materials, it is necessary first of all to select and justify the simulated external factors and their maximum values. When determining the allowable amplification of the selected external factor as compared to its influence under operating conditions, it is necessary to be guided by the following: at the maximum value of the external aging factor in artificial conditions, the physical and chemical aging processes must be identical to those occurring in real operating conditions. Since, taking into account this condition, we will be able to obtain the most qualitative and accurate indicators.
