N2  -  The aim of the study is to compare road geometric characteristics with standard road construction values. The study area is Tang-e-Sulak, protected area located in Bahmiy (Kohgiluyeh and Boyerahmad), at the southern Zagros forests. First, the existing road location was taken using GPS and then placed on a topographic map. In the next step, the slopes were graded (from 0-10, 10-20, 20-30, 30-40, 40-50, 50-60 and > 60 percent), then 11 samples were randomly selected on each slope. In the next step, the size of the samples was compared with the standard values (Booklet No. 131 and 161). The width of the running surface and path of the way were analyzed on the basis of analytical and other road geometric characteristics based on descriptive statistics. Soil samples were taken from each of the slopes’ grades. Data analysis was done by T-test and Pearson correlation in SPSS 22. The results show that the width of the road and the construction area of the road on the slopes 10-20, 40-50, 60-50, and 60 were less than the standard values and it is statistically significance (P<0.01), and in other slopes wasn’t significant differences. Analytical descriptive statistics showed that the average slope of excavation and embankment walls is 15% higher than the standard value. The results of soil texture analysis by unified classification method showed silty- clay texture.Analytical descriptive statistics showed that the average slope of excavation and embankment walls is 15% higher than the standard value.The results of soil texture showed siltyclay texture.
