This paper summarises the full scale accelerated research done during the past six years with the Heavy Vehicle Simulator (HVS) belonging to the Roads Branch of the Transvaal Provincial Administration (TPA). The research concentrated on the structural behaviour of pavements incorporating lightly cementitious base and subbase layers. Special failure mechanisms were identified which include aspects such as crushing failure of deep pavements and effective fatigue of shallow pavements. Improved in-situ pavement evaluation methods such as with the Dynamic Cone Penetrometer (DCP) are also described. Detailed information regarding various rehabilitation options for there pavements are given together with their HVS performance.
