Review of methodological approaches to planning maintenance work for road network operations

Introduction. The development of Ukraine's road network under current conditions is characterized by limited funding for road maintenance. At the same time, determining the scope and list of works based on the actual operational condition of the roads is extremely important, as it significantly affects the safety and comfort of road users, as well as the efficiency of vehicle operation. A standard norm is used to determine the planned scope of work, which is averaged for roads of the corresponding category. This simplifies calculations, but such an approach does not precisely establish the annual planned volumes of maintenance work for a specific section, as it does not consider its actual operational condition. Given the current level of funding, it is relevant to develop a methodology for determining the planned volumes and lists of maintenance work that is accurate enough, but does not require significant costs for road section inspections. Problem Statement. The determination of the scope of maintenance work is based on a comprehensive analysis of the road surface condition, forecasted traffic loads, and the allocation of budgetary resources. However, under martial law, the country’s priorities have shifted, with the focus on ensuring state defense, providing humanitarian aid, etc. Based on the current trends in the development of Ukraine’s road industry, the main task is the rational use of limited financial resources and maintaining roads in proper operational condition. The standards for the scope of maintenance work are approved in accordance with the Methodology for Determining the Funding for Road Construction, Reconstruction, Repair, and Maintenance (hereinafter — the Methodology) [1] and are averaged across Ukraine. According to this standard, a specific list and volume of works for 1 km of a national category II road is set, which is adjusted by correction coefficients and the length of the corresponding category sections to fit the required network, but does not take into account their actual operational condition. National roads usually have higher traffic intensity compared to local roads. Also, newly repaired roads significantly differ in operational condition from those that have not undergone repair for an extended period. Therefore, establishing a differentiated approach to updating the volumes of maintenance work for national and local roads is extremely important.
