The Division of Road and Transport Technology of the Council for Scientific and Industrial Research (CSIR) in South Africa has been involved in research and implementation of findings on all aspects of low-volume roads for four decades. It is from this work that the Division has acquired a vast base of knowledge on the unique conditions of the African continent both in terms of the use of materials under different climatic conditions and socioeconomic problems associated with road construction. The paper presents a brief outline of the type of work which has already been done and is now being done within the region, both on paved and unpaved low-volume roads along with some examples of each. It is also pointed out that (1) with the rapid urbanization presently occurring, the necessity to provide large lengths of access streets and commuter routes is going to increase dramatically; (2) the quality of the rural roads must not be allowed to deteriorate; and (3) environmental aspects will need to be investigated further with careful attention being paid to dust generation and the pollution of rivers through erosion from roads and associated structures.
