dc.description.abstract |
Although the use of Roller Compacted Concrete (RCC) is not new in South Africa, the use of it to construct roads is not that well known or studied. The Gauteng Provincial Department of Roads and Transport (GPDRT) in conjunction with CSIR Built Environment in South Africa and Cosal Consultants CC started a research program on the use of RCC technology for roads. Whereas RCC is normally constructed with a relatively low labor component using heavy mechanical equipment, one of the aims of this investigation was to evaluate the structural performance of RCC constructed with a relatively high labor component using hand-operated equipment. The evaluation was done using the Heavy Vehicle Simulator (HVS) of the GPDRT. This paper briefly details two investigations. One HVS RCC test was conducted at the CSIR innovation site and the other on a full-scale test road at Rayton, Gauteng. Through HVS testing it has been shown that this type of pavement performed well in the dry state, even when constructed on a substandard support system. Test results indicate that this type of pavement exceeded its predicted performance. The use of hand-labor for layer compaction is discouraged as this can lead to layer densities lower than acceptable standards, which result in poor performance. The importance of proper RCC mix design to mitigate the negative effects of shrinking and crack forming is highlighted in this study. |
