Author:Paige-Green, P; Pinard, MI; Mgangira, Martin BDate:Jul 2011Aeolian sands are widespread in many semi-arid to arid areas of the world and often provide the only economic source of construction materials for low volume roads. Experience in southern Africa over a number of decades has shown that provided ...Read more
Author:Paige-Green, P; Coetzer, K; Lea, J; Semmelink, CDate:17 Jun 2009The use of locally materials in low volume rural roads can result in significant cost savings. However, this is associated with an increased risk of premature distress or failure. A compromise needs to be found between the probability of ...Read more

Author:Verhaeghe, Benoit MJA; Maina, J; Paige-Green, P; De Beer, Morris; Du Plessis, LDate:01 Sep 2010Road infrastructure is a key driver in supporting and stimulating socio-economic development. The South African road network, similar to those of other countries, needs to accommodate a wide spectrum of roads, ranging from light road pavement ...Read more
Author:Paige-Green, PDate:Feb 2007One of the most important materials for the construction of high quality pavement layers in roads in South Africa is the Basic Crystalline group of rocks. The major deposits of these materials are associated with the dolerites and basaltic ...Read more
Author:Paige-Green, PDate:Jul 2004This paper briefly summarises the geological and geomorphological history of South Africa. This history is then related to various problems affecting the construction of roads in South Africa. These problems need to be identified early and ...Read more
Author:Wium, DJW; Ribbens, HDate:Feb 1986A method is described for setting the speed limit for a particular road section. Several speed limits based on different criteria are described for each of nine traffic and road factors. The most appropriate speed limit for each relevant ...Read more
Author:Rust, FC; Mahoney, JP; Sorenson, JBDate:1998The authors have attempted to show that local differences in pavement practices and climate are typically not all that different (with the exception of countries such as South Africa). Further, the transfer of technology is difficult given ...Read more
Author:Paige-Green, P; Verhaeghe, Benoit MJADate:Oct 2018The inevitable impacts of climate change on the already stressed low volume rural road networks in Africa will have dire consequences in many countries. These networks generally suffer from a lack of appropriate construction standards and ...Read more
Author:Paige-Green, P; Verhaeghe, Benoit MJADate:Oct 2019It has been estimated that by the end of the century, $150 billion will be required to repair and maintain existing roads in Africa, the majority of which will be low volume rural access roads. Research into the prioritisation and adaptation ...Read more
Author:Paige-Green, PDate:Nov 2009During the early 1980s a number of problems related to the loss of stabilization and disintegration of stabilized layers in roads (lime and cement) were reported in South Africa. This led to many comprehensive investigations and it was shown ...Read more
Author:Paige-Green, PDate:04 Jun 2009An investigation into the performance of 57 sections of road in South Africa identified by the Provincial Road Authorities as being constructed using marginal quality base course materials has been carried out. The investigations has shown ...Read more
Author:Anochie-Boateng, Joseph; Tutumluer, EDate:Jun 2009Shear strength properties of three oil sand materials were determined in the laboratory by simulating field loading conditions of large capacity mining trucks and shovels. Both monotonic triaxial compression and direct shear tests were performed ...Read more
Author:Horak, E; Verhaeghe, Benoit MJA; Rust, FC; Van Heerden, CDate:Oct 1994Roads with high traffic volumes are synonymous with high road related noise levels. In Johannesburg road related noise pollution is recognised as a negative environmental impact. The Noise Pollution Unit of Johannesburg City Council regularly ...Read more
