Comparingthe expenses of forest road cut and fill operations with standard rules (Study Area: Northern Forests of Iran)

Forest roads are one of the important feasible ways to forest areas in order to utilization, afforestation, forestry planning and recreation. Road development in forest has some negative and positive effects on environment. Thus, it is necessary for standardize of theirs geometric and technical characteristics. This research carried out for investigation and assessment of created forest road, considering to role of performed edaphic operations in forest roads on making expenses and optimum using of site potential in Neka - Zalemrrod catchment's. These watersheds located in between Neka and Behshahr cities in Mazandaran province (North of Iran) and included high diversity considering slope, aspect and earth structure. In this study, edaphic operations volume of a forest road section, viewpoint with and without standardized were surveyed. Also, excess expenses due to volume increasing of edaphic operations were calculated. An important result is significant differences between cut and fill volume and finally, total of expenses collection. According to the difference between calculated cut and fill volume in standard condition (10645.44 and 4153.88 m3) and volume of performed operations (12511.59 and 4284.75 m3) are considerable and followed an expenses increasing equal to 16967000 Rials, thus it is not acceptable economic consideration.
