Method of physical and functional wear assessment in determining the quality condition of road bridges

Introduction. Assessment of the qualitative condition of road bridges is a complex process that involves the analysis of physical and functional deterioration of structures. Physical deterioration is associated with deterioration of materials and loss of strength of elements, while functional deterioration is manifested in a decrease in the bearing capacity and deformability of the bridge. Problems. To determine the level of wear, a comprehensive method is used, including visual inspection, calculation estimates and experimental studies. In addition, a differentiated method is used, which allows comparing actual values with design values and drawing conclusions about the quality of individual elements and the structure as a whole. Objective. The expert method is an important addition to other methods of assessing the technical condition of bridges. Materials and Methods. It allows to take into account factors that are difficult to formalize and provides a comprehensive understanding of the condition of the structure. However, in order to obtain reliable results, it is necessary to carefully approach the formation of an expert group and the organization of the assessment process. Results. Assessment of the qualitative condition of bridges is critical to ensuring the safety of their effective operation. The qualimetric model offers a detailed and structured approach to assessing the physical deterioration of a bridge by dividing the entire structure into key elements and evaluating each of them according to various parameters and provides a comprehensive assessment of its condition.
