Aeolian sands as material to construct low-volume roads

Author: Paige-Green, P ; Pinard, MI ; Mgangira, Martin B Date: Jul 2011 Aeolian 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
Appropriate use of locally available materials in concrete, bituminous surfacings and layerworks for roads in rural areas

Author: Paige-Green, P ; Coetzer, K ; Lea, J ; Semmelink, C Date: 17 Jun 2009 The 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
The CSIR contribution to the Revision of the SA Road Pavement Design Method (SAPDM)

Author: Maina, J Date: Oct 2012 In this presentation the author outlines the CSIR contribution to the Revision of South African Pavement Design Method. Read more
CSIR’s contribution to the development of innovative technologies and solutions for enhanced road system performance

Author: Verhaeghe, Benoit MJA ; Maina, J ; Paige-Green, P ; De Beer, Morris ; Du Plessis, L Date: 01 Sep 2010 Road 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
Durability testing of basic crystalline rocks and specification for use as road base aggregate

Author: Paige-Green, P Date: Feb 2007 One 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
Geology and engineering geology of roads in South Africa

Author: Paige-Green, P Date: Jul 2004 This 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
Guidelines for setting speed limits

Author: Wium, DJW ; Ribbens, H Date: Feb 1986 A 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
An international view of pavement engineering

Author: Rust, FC ; Mahoney, JP ; Sorenson, JB Date: 1998 The 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
Making Africa’s roads more resilient to climate change

Author: Paige-Green, P ; Verhaeghe, Benoit MJA Date: Oct 2018 The 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
The prioritisation and adaptation for climate change resilience of rural access roads

Author: Paige-Green, P ; Verhaeghe, Benoit MJA Date: Oct 2019 It 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
Reassessment of problems affecting stabilized layers in roads in South Africa

Author: Paige-Green, P Date: Nov 2009 During 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
Recommendations on the use of marginal base course materials in low volume roads in South Africa

Author: Paige-Green, P Date: 04 Jun 2009 An 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
Shear strength properties of naturally occurring bituminous sands

Author: Anochie-Boateng, Joseph ; Tutumluer, E Date: Jun 2009 Shear 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
Use of porous asphalt on major roads in Johannesburg

Author: Horak, E ; Verhaeghe, Benoit MJA ; Rust, FC ; Van Heerden, C Date: Oct 1994 Roads 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
