at the top of the pipe, if heavy traffic is to pass over it. For example; 160mm Pipe – trench width should be 460mm. Above the crown of the pipe any width will do. I always throw in a bed of compactable gravel, sand or fine scoria for the pipe bedding and surround.
In this example HDPE pipe only contributes 5% whereas RCP contributes 90% of the structural strength of the soil/pipe system. Therefore, post installation inspection is imperative to ensure the constructed flexible soil / pipe system was properly built. 3” 4” 12”
The eedment material may be imported, such as a crushed stone, or it may be the ("native") material excavated from the trench to make room for the pipe. The eedment material should provide adequate strength, stiffness, uniformity of contact (i.e., completely envelop the pipe) and stability to minimize deformation of the pipe due to earth pressures.
