A pioneer road is created at the highest with the Slice by drifting substance from and along with the felled trees. Initial excavation and aspect Solid reduction can consequently be saved to the minimum. When rock is encountered, Dust drifted against or on top of trees will type A brief bridge to allow passage of construction products. True excavation is commenced about 10 to 12 meters from your loader by cutting a blade-broad trench and drifting the fabric to it. Free content which escapes through this process is caught from the felled trees and slash. Since the Lower gets further content will fall In the trench from each side (Figure 113).
