Abstract

Potholes are a liability in the First World and in the Third World countries. In South Africa they represent a deteriorating road network and in the Mpumalanga Province road network potholes have become the visible symbol of a failing road system. There seem to have evolved a special case of the problem, distinct in occurrence, frequency, nature and size. This paper is an attempt to investigate the underlying issues behind this scourge. It purports to offer a comprehensive account of the problem, assessing the current and future status of the problem. In order to enhance this investigation this paper will look at the pothole problem as a general world phenomenon, as a South African problem and comprehensively as the Mpumalanga Province road network problem. This approach is presumably supposed to lead to a diagnosis of sorts and an investigation based prescription derived.
