I am wondering what is the meaning of a proper road? I suppose it is a road that serves the purpose. So it would depend on the location, the nature of traffic and amount of traffic on the road. In any case, if it should be considered as proper or good, it should provide a fast traffic movement, it should be safe and it should be pleasant. With all these criteria, there would be a trade off between quality and cost. I suppose like every thing else in life where there is such a trade off, lowest in quality does not mean lowest in cost. This is especially true if one considers the cost as a cost over the life time of the product, in this case the life time of road. Moreover, if the cost includes the total cost-not just the construction and maintenance of the road but also the costs that arise due to the condition of road such as the wear and tear of tyres, other vehicle repairs, but more importantly, cost of human lives as a result of accidents.
To be continued....
