| Title of the article | Determination of the evenness and safety of passage on bridge structures |
| Abstract. | The main problem in the diagnosis of highways is the lack of a methodology for determining the international index of evenness in areas with bridge structures and its correlation with the safety indicator of passage through bridge structures. Deformation joints, vibrations of superstructures and other features of bridges lead to an overestimation of the values of the evenness index, and, as a result, to an overspending of budget funds for repairs allocated depending on the measurement results. The purpose of the work is to study the peculiarities of the influence of bridge structures on the evenness index and to find approaches to determining the mathematical dependence of the safety indicator for bridge structures on the evenness index. The main objectives of the study are to develop basic models of single artificial bumps; to conduct road laboratory tests on control sections with the placement of artificial bumps and the measurement of evenness, to process experimental data and to evaluate the effect of the size and number of single artificial bumps on the evenness index. The paper presents the results of studies of the effect of single artificial bumps on the evenness index on road sections with and without bridge structures. The significance of the work lies in the fact that the results of experimental and computational studies are the basis for the development of a mathematical model of the dependence of the safety index of passage on bridges on the evenness index, which in turn will optimize the cost of repair and maintenance of highways without compromising the safety of passage on bridge structures. |
