Evaluation the Maintenance Situation of Road in Arasbaran Region

Forest roads are basic infrastructures for management of forested areas. Sustainable management of roads depends on regular and timely forest road maintenance. Road inventory is as an important tool to recognize the needs of roads and do corresponding correction operations. GIS can be a powerful tool for acquirement, analysis and management of data in road management. The purpose of this study was to obtain the required information for road management in Kaleibarchay watershed, Arasbaran region, to provide practical maintenance and monitoring solutions. To do this, 131 samples were selected and for each sample some data such as road gradient, template, problems of surfacing and slope stability were collected. Then spatial data and corresponding database were developed in ArcGIS and were compared to standard values. According to the results cross-slope has the highest consistency with standard values. 25.19% of the road length was without any sign of surfacing problems. Among surfacing problems rutting has the highest and pothole has the lowest abundance and cut slope had more stability problems than fill slope. In order to better management of drainage system, we suggested some places for new cross drain including culverts and fords. The results of this research showed the potential application GIS for forest roads management.
