The purpose of this study is to compare road geometry with standard road construction values. The studied area is Tang-e-Sulak, located in the city of Bahmiy (Kohgiluyeh and Boyerahmad Prov.), a protected area with its tourist, recreational and natural attractions in the southern Zagros forests. In this research, the existing road position was first taken using GPS and then placed on a topographic map. In the next step, the slopes were graded (from 0 to 10, 10 to 20, 20 to 30, 30 to 40, 40 to 50, 50 to 60 and more than 60 percent), then 11 samples were randomly selected on each slope. In the next step, the size of the taken samples was compared with the standard values (Booklet No. 131 and 161). The width of the running surface and right of way were analyzed on the basis of analytical statistics and other road geometric characteristics based on descriptive statistics. Soil samples were taken from each of the slopes of the slopes, and a soil sample was selected randomly for soil texture detection. Data analysis was done by T-test, Pearson correlation and SPSS software. The results showed that the width of the rudder and the constructional area of the road on the slopes (10-20, 40-50, 60-50, and 60) were less than the standard values and in the 1

Forest Roads are the main element of recovering, conserving and harvesting of natural resources. The current research has down in order to spatial locating qualitative characteristics of road pavement and schedule conservation and maintenance projects in main road, 1, 2, 3 roads in ShastKalateh Forestry plan, Gorgan, Iran. First all of the roads were sampled 100% defects of Pave, Technical Buildings, Horizontal curve were recorded. As well as, Landslide and Erosion point that make the problem were recorded then restoration methods were determined. Results showed in pavement part, slump and vegetation cover on the travel way were the important problem of roads. In addition Landslide and Erosion and trees in Horizontal curve were the other dilemmas of the roads. Subsequently, annual and Periodic reconstruction schedules have been recommended.
