Mathematical model for optimizing the repair plan for the international roughness index IRI
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The authors analyzed the existing regulatory documents and studies on the road surface evenness impact on the traffic flow speed, the transportation and traffic safety costs. Currently available methods of forming a plan of repair work are focused on the use of the roads diagnostics results according to the evenness level of the

Jurnal Syntax Transformation, 2023 The condition of road pavement is going to decrease during its service life. To keep a pavement functioning, maintenance must be continuously performed. However, the maintenance that has been carried out so far has not been carried out optimally because the budgeting system is still carried out annually based on the results of a road condition survey ...

The Profiling of International Roughness Index (IRI) Based on Lagrangian Method
World Journal of Engineering and Technology, 2018 The phenomenological equations of motion for the international roughness index (IRI) have been reviewed and discussed in terms of Lagrangian method in physics. The current paper proposes a practical, two-dimensional model for studying essentially three-dimensional, vibrating, and mechanical systems (vehicles).

Intelligent Transportation Infrastructure, 2022 Abstract The International Roughness Index (IRI) is one of the most commonly used indicators to measure pavement surface smoothness. This paper uses the data obtained from the Specific Pavement Studies-3 (SPS-3) of the Long Term Pavement Performance (LTPP) program to study the influencing factors of the International Roughness Index of ...
