Investigation into the adequacy of drainage on road performance: a case study of Bata Bata, Entebbe road Namasuba.

Abstract

Water is the main contributor to the failure and damage of roads. . Road surface drainage deals with the drainage of storm water runoff from the road surface and the surfaces adjacent to the road formation. The damage to the road can be reduced if the flow of water is controlled. Minor damages can easily be repaired as part of the regular maintenance provided to the road and its structures. If the flow of water is not properly managed, the deterioration of the road will be more serious and occur more rapidly.(Rokade, 2012) Having a drainage alone is not sufficient, the drainage must be well designed and of good quality and since poor drainage is one of the major factors that have resulted into early road distresses and structural failures. This form of failure is normally presented inform of potholes, reduced strength of pavement layers and sub grade, deep road side gullies and depressions in road pavements and hence flow of traffic is disrupted and regular maintenance is required in order to preserve them in their original construction form and serve their purpose.
