CALCULATING THE WEAR INDICATORS OF MOUNTAIN ROADS' STRUCTURES AND THEIR EFFECTS ON THE ENVIRONMENT'S VULNERABILITY

The lack of clear boundaries of the vertical climatic zonality of mountainous countries in the norms for building climatology leads to errors in the timing of the interrepair work of highways. Given in GOSTs and other regulatory documents, these terms are of an average nature. For this reason, pavement structures and vehicles (road transport system) are subjected to premature wear and tear, and harmful emissions into the environment of mountainous areas increase. In order to increase the durability of pavement structures of mountain roads and reduce harmful emissions into the environment, a method is proposed for determining the optimal time between repairs of mountain roads, taking into account the integrated indicators of their wear, under the influence of natural and climatic factors of mountain conditions. It has been determined how these elements affect how ecologically vulnerable mountainous places are, and the ideal time frame for lowering the need for mountain road maintenance has been provided. The effectiveness of mathematical models and the reliability of the working hypothesis on the proportionality of the optimal periods for reducing overhaul life and the environmental vulnerability of mountainous areas have been proved.
