The use of stabilised layers is cost effective in road construction in South Africa. Some stabilised materials have however been found to be susceptible to erosion. To identify erodible materials the Erosion Test was developed in 1989. This report, discusses the state-of-the-art of erosion testing in South Africa. The report presents the results of the repeatability and reproducibility study undertaken to determine the precision of the Erosion Test. The Erosion Test is the compared with the two durability tests currently used in South Africa. Based on information currently available, new criteria for the Erosion Test are proposed for flexible and rigid pavements. The use of the new Department of Transport Erosion database created as part of this report (disk on inside cover) is then disucssed. Finally conclusions concerning erosion and durability testing are presented along with recommendations and suggestions for further research.
