There is a significant need in South Africa for the upgrading of suburban streets with a solution that performs well, is cost-effective, and requires minimal maintenance. There is also a need for job creation in road construction, using local labor when possible. The ultrathin reinforced concrete pavement (UTRCP) technology, one such solution, was developed by the Council for Scientific and Industrial Research in South Africa and has been implemented in a number of projects. The technology was developed for suburban streets and roads carrying fewer than 2,500 vehicles/day and is constructed with labor using light plant. UTRCP consists of a lightly reinforced, 50-mm-thick, 30-MPa concrete layer that is generally constructed on shaped and compacted in situ material; modification may be required if the in situ material has a high plasticity index. Experimental work was conducted by testing trial sections of UTRCP supported by various subbase layers. This included static testing, rolling wheel load testing with a heavy vehicle simulator, and evaluation of the performance of trial sections under normal traffic. The results of the experimental work and the subsequent proposed structural designs used in implementation projects are described. The technology has been implemented in various projects in suburban townships in South Africa in the Gauteng Province. The practical lessons learned from these projects are described. Lastly, criteria for the subbase design of pavement structures containing the UTRCP layer are proposed, and further work is suggested.

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 the CSIR Built Environment and Cosal Consultants CC started a research programme in the use of RCC technology for roads. Whereas RCC is normally constructed with a relatively low labour component using heavy mechanical equipment, one of the aims of this investigation is to evaluate the structural performance of RCC constructed with a relatively high labour 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 conducted at the CSIR innovation site and the other test on a full-scale test road close to Rayton, Gauteng. The second investigation started in July 2013, and this paper deals mainly with the construction and initial test results of this test.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 labour for layer compaction is discouraged as this can lead to layer densities of 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. 165
