The heavy vehicle simulator (HVS) of the Department of Transport was used in the evaluation of the Van Reenen's pass rehabilitation project. This project included a section where 70 per cent reclaimed bituminous material was used in the base layer. The in situ fatigue characteristics of this base layer (recycled asphalt) and the wearing course layer (new premix) were studied as well as the permanent deformation characteristics with and without the artificial introduction of water into the two subbase layers. The effect of temperature on the permanent deformation characteristics of the in situ asphalt layers was also studied. Trenches cut through the test sections enabled the origins of the permanent deformation to be observed. The investigation stressed again the importance of providing adequate support to relatively stiff asphalt layers in a pavement structure used for heavy traffic conditions. (Author/TRRL)
