Within this paper, methods and devices for collecting data on pavement characteristics are presented. Emphasis is placed on the data related to the structural and mechanical characteristics of the pavement. An overview of the theoretical foundations of the methodology for designing reinforcement and reconstruction of roadway structures is given, as well as an analysis of methods for dimensioning the reinforcement of roadway structures using measured deflections. The procedure itself is shown on the example of a State road Šid – Kuzmin.
