Assessment of the reliability of operated sections of highways

Background. The main objective of this study is to develop a methodology for checking the actual reliability of road surfaces based on the dynamics of changes in pavement smoothness, estimated vehicle speed, and estimated service life. The study introduces proprietary quantitative criteria, such as the road structure operational reliability coefficient and the road surface service life coefficient. The study is related to observing changes in road surface smoothness and its impact on performance characteristics. Assessing the wear and tear that occurs during operation is especially important for determining repair periods and the required amount of work. The article provides examples of smoothness measurements on road sections with varying traffic intensities, which allows us to draw a conclusion about the different rates of pavement condition deterioration and identify areas that are most susceptible to deformation.

Purpose. Consists in developing and testing a methodology for assessing the condition of road surfaces, with an emphasis on analyzing the evenness and performance characteristics of road structures. The main task is to integrate quantitative indicators and mathematical models that will allow more accurate determination of the timing and volume of necessary repairs.

Materials and methods. The article presents a methodology for assessing the actual reliability of road surfaces, developed on the basis of the dynamics of changes in the smoothness of the pavement, the estimated speed of the vehicle and the estimated service life. The methodology includes the author's developed quantitative assessment criteria, which include the coefficient of operational reliability of the road structure, the operational service life of the pavement and the coefficient of the service life of the road pavement.

Results. Based on the results of the study, reliability assessment criteria have been developed that can be useful for road management bodies and for repair planning. These criteria allow not only to identify areas requiring repair, but also to optimize the resources spent on its implementation. The study proves that the use of mathematical models and quantitative indicators can significantly improve the road surface management system, increasing safety and comfort for users.
