Horizontal and Vertical Alignments of Forest Roads
2014
Nacrtak Forest roads should be in a condition to bear traffic load at every moment. They can endure traffic load only if their dimensions are within the limits prescribed. The dimensions of forest roads depend on: the soil type, category of forest road, and vehicles that use them. In this paper, forest roads constructed on two types of substrates (terrain category 3 and 4; Protic 1970) were observed, and dimensions of horizontal and vertical alignments of forest roads were determined. According to the results of this research, it was concluded that the state of forest roads is satisfactory in terms of traffic. However, it is necessary to pay attention to longitudinal slope of forest road carriageway and cross slope of carriageway in the curves that depend on the longitudinal slope of carriageway and radius of horizontal curve.
