THE PERFORMANCE OF LIGHT PAVEMENTS IN THE WESTERN ORANGE FREE STATE

In the current climate of rising costs and shortage of funds for road building and maintenance, it is becoming increasingly difficult to provide all weather access on paved roads to many rural areas. Traditional pavement designs for interurban roads are too costly and inappropriate for low volume roads. Six sites in the western Orange Free State were investigated in this study, where information regarding the performance of light pavements was gathered from which guidelines for the design of these roads could thus be formulated. The aim of this paper is to document the results of the investigation and to propose design guidelines. The analysis showed that the roads would carry E0 to low E2 traffic during a 20 year design life. It was concluded that: - light pavements have provided good performance in the past and are suitable for low volume roads, provided that they are designed, constructed and maintained with this purpose in mind; - the quality of particularly the base material determines the life of the pavement, rather than the structural capacity.
