%X Nowadays, the pavement maintenance programming and preservation are considered as a necessity in road agencies. In other words, the road agencies have realized that using the decision support system such as pavement management system (PMS), which assists them to find cost-effective maintenance solutions, could be useful for managing pavement networks. Budget limitation compels road agencies to prioritize the maintenance of pavements. Actually, maintenance prioritization, which depends on various factors like pavement conditions, traffic volume, performance standards and financial constraints, is a necessity for the optimal use of the resources and selection of the better choices. The pavement management system, as a strategic tool, has been organized by collecting and retaining large amounts of data. The Geographical information system (GIS), as a practical tool, can be appropriate for data integrating, collecting, managing, analyzing and output presenting in PMS. Factors such as the significant cost of data collection, the lack of long-term pavement performance data and the lack of developed and calibrated pavement deterioration models, are important reasons that can affect the implementation of pavement management system and the pavement maintenance prioritization. In the absence of these main needs, providing a new and simple approach can be used as a short-term management decisions for pavement maintenance management. This paper, develops a short-term maintenance management approach in 2 scenarios (with and without budget limitation) at the network level, wherein prioritization is based mainly on pavement condition, treatment cost, importance of road performance and communication role (connectivity) and traffic range in the GIS environment. Furthermore, crack sealing, patching, and thin overlay have been chosen as maintenance activities. To check the results of the proposed method, the surface distress of flexible pavements in Ilam province, Iran, were investigated in 2013 through rapid visual evaluations. Moreover the geographical information system (GIS), as a strategic asset management tool, has been used to display pavement section distress and the result of prioritization.
