Other major reasons leading to potholes on the roads of Hyderabad is the unfinished projects coupled with badly designed roads.
Dealing with the road design first, the existing ones are design flat, without any slope factor. This results in the water stagnating in the small and negligible troughs that are created due to factors like bad compacting of the raw material beneath and the melting of the tar due to high temperatures. When water stagnates into such smaller pools, it creates an unexpected bounce coupled with friction when vehicles pass through them, and this results in the gravel losing its tar bonding.
This situation, when neglected, snowballs into bigger potholes, and finally makes the whole surface uneven and unfit to drive on.
A well-laid road should ideally be a package from wall to wall, providing space for all elements using the surface. These elements can be active ones like storm-water, pedestrians and vehicular traffic, which are bound to change with time, and then there are passive elements like soil and shrubs or trees planted on the road-side.
Non of these elements should be allowed to over-power the base structure (road). Once the base structure is disturbed, a conflict between these elements starts rendering inconvenience to all of them.
The above image shows the cross section of a well-laid two-lane road (one-way), showing the provision for both the active and passive elements using it. The design is simple yet effective.
It is quite obvious that a little research and the willingness to invest on a better design in the initial stages proves to be maintenance-free and less expensive for the authorities in the long-run.
