  • 摘要:The object of research is the process of a comprehensive assessment of the qualitative state of a waterlogged section of a road. Natural and climatic factors affect the state of the road due to changes in the conditions of the water-thermal regime and the movement of vehicles. Water, sudden temperature fluctuations, the impact of heavy transport play a key role in the life cycle of any transport structure, affecting its transport and operational characteristics. The definition of a complex indicator of the qualitative state is based on a set of individual indicators, it is comprehensively characterized taking into account the influence of the weightings of each parameter and the structural element of the highway. This is taken into account in the multilevel qualimetric model, which consists of two main groups of physical and functional wear. Indicators of physical wear and tear change over time and are characterized by compliance with certain regulatory indicators and requirements. Functional – do not change over time, but depend on the needs of consumers of transport services. The choice of the number of model levels depends on the weight of the technical and functional characteristics of the road section. Information about the site and its constituent properties increases with the number of levels. Their optimal number determines the volume of measurements and calculations when obtaining a complex indicator of the quality state. The research results made it possible to develop a comprehensive method for assessing the quality state of a waterlogged section of a road where it is necessary to arrange a drainage system. The developed method is based on an expert approach for determining physical and functional indicators, the number of which is determined depending on the parameters of the road. The nomenclature of indicators of the qualitative state of a waterlogged section of the road has been substantiated and a model with an optimal number of indicators has been formed, comprehensively and in full, allows one to characterize all its structural elements in terms of physical and functional wear.
