摘要：	A brief background is given to the implementation of a pavement management system in the Transvaal Provincial Administration in the Republic of South Africa. The system has been in place for 8 years and provides valuable information in terms of the overall condition of the road network and its deterioration over time. The pavement management system primarily utilizes visual inspections to assess the network condition and to prioritize resealing and rehabilitation. The current visual inspection procedure is described briefly, and the various changes that have been made and problems that have been experienced with this procedure over time are described. In view of the fact that reseals are prioritized on the basis of road condition, the poorer roads have been sealed during periods of severe budget constraints. This has led to neglect of the better-quality roads, which in their turn have deteriorated significantly. More recently the approach to resealing has been changed so that resealing is prioritized on a cyclical basis for each road, with condition playing a smaller role. The current intention is to try and maintain the better roads and to abandon the very poor roads because of severe budget constraints. The road network condition is deteriorating, and funds have been reallocated from other sources to prevent the deterioration. A combination of user operating costs and road maintenance costs is used to prioritize the rehabilitation and reconstruction work. The problems in carrying out rehabilitation work in the past and with present procedures in a period with decreasing budgets are described.
