Paper presented at the 23rd Annual Southern African Transport Conference 12 - 15 July 2004 "Getting recognition for the importance of transport", CSIR International Convention Centre, Pretoria, South Africa. This paper briefly summarises the geological and geomorphological history of South Africa.
This history is then related to various problems affecting the construction of roads in South
Africa. These problems need to be identified early and countermeasures taken to ensure that
premature and costly road failures do not occur. The major problems discussed include those
related to expansive, collapsible, dispersive, erodible and very soft soils as well as material
durability and slope stability. It is interesting, but somewhat worrying, to note that little
development in these areas has taken place since the hey-days of research between the mid
1960s and the late 1980s.
