Abstract: Hot Mix Asphalt (HMA) surfaced roads provide good riding quality when properly constructed, but there are serious distresses associated with HMA, and asphalt rutting is one of them. The existence of rutting on roads results in ponding of water in the wheel tracks, increasing the potential for aquaplaning during wet weather, poor riding quality and increasing vehicle operating costs. Fatigue cracking compromises the structural integrity of the pavement and enables water to penetrate into the pavement structure, causing secondary distress. This paper only concentrates on rutting. There is a need for developing improved laboratory testing methods and appropriate acceptance criteria for rutting in South Africa. The latter was echoed during the 9th Conference on Asphalt Pavement of Southern Africa. The outcomes of this study will address some of the issues surrounding laboratory tests for evaluating rutting
