The assessment of unsealed roads in South Africa has, up to now, been done on an ad hoc basis with a variety of individual standards and has produced highly subjective results. A standard visual assessment manual has been developed to provide a single, unified objective system of unsealed road evaluation in South Africa and southern Africa. The assessment techniques, as well as standard descriptors of the various distress modes, are clearly defined in the document. Examples of the content and application of the document are provided and discussed.
