Finding lasting solutions to the early deterioration of constructed roads in Nigeria.

Abstract

The socioeconomic benefits of having good roads is hardly realized in most developing countries, due to the fact that most constructed roads tend to deteriorate very rapidly before their expected life span. Several factors have been identified by different researchers to be the cause of this problem. This paper tried to find solutions to some of these factors using three phases of route survey and design of roadways, namely; route location, data acquisition, and geometric design. The results showed that most of the factors that facilitate early deterioration of constructed roads could be solved through the processes involved in the three phases of route survey and design of roadways. The paper concluded that route survey and design of roadways thoroughly addresses and solves most of the factors that facilitate early deterioration of constructed roads.
