In the road maintenance system, there are several options for repair and maintenance. But due to resource constraints, one should take into account the various options available to provide the lowest cost with the desired goals and prevent future losses. The purpose of this study was to investigate the management of rural roads in Mazandaran province. One of the most important steps in the management system is to evaluate the current conditions of the pavement, which uses a variety of indicators. One of the indicators derived from the analysis of failure data analysis is the PCI index, which is one of the best indicators for assessing the failure of Iran's roads. In this research, after field observations and evaluation of failures and analysis with Micro Paver software, it was determined that rural road pavements had "suitable conditions" with an average of 76PCI. Asphalt pavement, which represents 87% of the pavement inventory, had an average PCI average of 74. Concrete pavements, which constitute 13% of the pavement inventory, were slightly higher than the 87 PCI. The results indicate that the projected budget is currently 2.0M / YR (approximately), possibly leading to a 6% decline in the overall PCI, as well as an increase in M & R stagnation over the next five years. The 7.1 M / YR budget was set to eliminate the recession, which achieved the lowest total cost during the five-year analysis period.
