Development and implementation of ultra-thin concrete road technology for suburban streets in South Africa

Author: Louw, MR ; Rust, FC ; Bergh, AO ; McKay, AH Date: 2011 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. In addition, there is also a need for job creation in road construction, ... Read more
Development of a road materials database for Gautrans

Author: Paige-Green, P ; Jones, DJ Date: Mar 2004 The data required for a road materials database was identified and a basic structure formulated during 2003. A set of Excel workbooks and associated worksheets was developed as a foundation for the database and as an interim means of gathering ... Read more
Development of a road materials database: Interim Report: 1st draft

Author: Jones, DJ ; Paige-Green, P Date: Mar 2003 The data required for a road materials database has been identified and a basic structure formulated. A set of Excel workbooks and associated worksheets has been developed as a foundation for the database and as an interim means of gathering ... Read more
The effect of poor drainage on pavement structures studied under accelerated testing

Author: De Beer, Morris ; Horak, E Date: 1987 Most of the structural failures in road pavements are in one way or another associated with excess water trapped within the pavement structure owing to poor drainage. The combined effect of traffic loading and trapped water within the pavement ... Read more
Evaluation of a nano-silane-modified emulsion stabilised base and subbase under HVS traffic

Author: Rust, FC ; Akhalwaya, Imraan ; Jordaan, GJ ; Du Plessis, L Date: Oct 2019 This paper describes the findings of a Heavy Vehicle Simulator (HVS) test on road D1884 in the Gauteng province of South Africa. The pavement structure was rehabilitated using an anionic nano-silane modified bitumen emulsion stabilising agent ... Read more
Evaluation of precast concrete slabs using a heavy vehicle simulator

Author: Kohler, E ; Harvey, JT ; Du Plessis, L ; Theyse, HL Date: Oct 2008 Precast slabs are considered an attractive pavement option for rehabilitation or reconstruction cases where traffic closures of less than eight hours are required. Benefits include long life expectancy of concrete cast in factory-controlled ... Read more
Fatigue and rutting performance of conventional asphalt and bitumen-rubber asphalt under accelerated trafficking.

Author: Rust, FC ; Harvey, JT ; Verhaeghe, Benoit MJA ; Noakes, W ; Van Kirk, J Date: Oct 1994 The Californian Department of Transportation commissioned a pilot project to evaluate the potential of the Heavy Vehicle Simulator (HVS) for conduction pavement studies. The effect of channelisation of traffic on the rutting behaviour of a ... Read more
First level analysis report: comparative testing of HVS Mk IV+ and HVS Mk III on road D2388 near Cullinan

Author: Morton, B ; Theyse, HL Date: Mar 2003 After many years of owning and operating a Heavy Vehicle Simulator (HVS) Mk III, Gautrans acquired a HVS Mk IV+ in May 2002. In addition to the advanced features that this machine possesses in comparison to its predecessor, the HVS Mk IV+ ... Read more
Heavy vehicle simulator and laboratory testing of a light pavement structure for low-volume roads

Author: Theyse, HL ; Steyn, WJVDM ; Sadzik, E ; Henderson, M Date: Jun 2006 Developing countries such as South Africa have an urgent need to create road infrastructure for rural access and urban mobility. Many of these roads will operate under low traffic volumes and only require a sealed, light pavement structure. ... Read more
Heavy vehicle simulator testing of trial sections for CALTRANS.

Author: Rust, FC ; Du Plessis, L ; Verhaeghe, Benoit MJA ; Grobler, JE Date: Oct 1993 Internationally, interest in accelerated pavement testing (APT) is increasing, in particular testing with mobile machines which allow the performance of in-service roads to be assessed. The Californian Department of Transportation (CALTRANS) ... Read more
Implementation of the Gautrans LTPP protocol at three sites

Author: Paige-Green, P Date: Mar 2004 This document describes the implementation of the Gautrans LTPP protocol. Three LTPP sections at existing HVS test sites have been located and market out in accordance with the LTPP protocol developed for Gautrans. Much of the initial ... Read more
Laboratory evaluation of road construction materials enhanced with nano-modified emulsions (NMEs)

Author: Akhalwaya, Imraan ; Rust, Frederik C Date: Jul 2018 Nano-modified emulsions (NMEs) have recently been used successfully across a number of trial projects in South Africa. Following the development of initial draft design approaches for NME stabilising agents, the Council for Scientific and ... Read more
