Figure 6.3 Inadeqate surface drainage.
Figure 6.4 Typical Drainage deficiencies associated with cut and fill.
In the design of the vertical alignment of roads, it is advisable to try to avoid cutting into the ground to reduce the risk of encountering subsurface water. Thus, the “depressed pavement construction” shown in Figure 6.4 should be avoided except where soil moisture conditions are suitable or the drainage systems effectively eliminate water-related problems.
