A PAVEMENT MANAGEMENT SYSTEM FOR THE NATIONAL ROADS OF SOUTH AFRICA

This paper was presented at session 13 - pavement management systems 1. A network of some 6000 km of national roads is being constructed in South Africa by the division of national roads. These roads are generally of freeway standard and therefore represent a high investment per unit length. Attention has been given to developing a pavement feedback system as an aid to managing the maintenance requirements of the pavements satisfactorily. This involves the storage of a large volume and variety of data which include the results of surveys with routine equipment, visual assessments, construction details, and so on. The storage and manipulation of these data have been incorporated into the data management software of the general information system of the division. This paper gives an overview of this pavement management system now in the initial stages of implementation. It describes the approach by which data are processed in a form that can be used in conjunction with subjective envaluation to determine maintenance requirements. The models are necessarily tentative because sufficiently accurate relationships between the variables have not yet been established. This feedback, however, will make it possible to study the outcome of various maintenance strategies and to review the models under which the management systems operates. (TRRL)
