Application of the portable pavement seismic analyser (PSPA) for pavement analysis

Author: Steyn, WJVDM ; Sadzik, E Date: Jul 2007 In this paper the concept behind the Portable Seismic Pavement Analyser (PSPA) is discussed, followed by information on a study conducted for the Gauteng Department of Public Transport, Roads and Works (GDPTRW). Data were collected from a ... Read more
Applications of observational techniques in pavement engineering

Author: Steyn, WJVDM Date: May 2007 Although the available observational techniques are used in all aspects of life, this paper focuses on those aspects where the applications are specifically dedicated to pavement engineering. The objective of the paper is to demonstrate how ... Read more
Evaluation of deformation response of HMA under APT and wheel tracking tests

Author: Denneman, E ; Steyn, WJVDM ; Maina, JW ; Sadzik, ES Date: Oct 2008 This paper is based on a study into the rutting performance of HMA which forms part of the larger research initiative. The objective of this phase is to identify and develop appropriate test protocols and associated acceptance criteria for ... Read more
Evaluation of issues around road materials for sustainable transport

Author: Steyn, WJVDM ; Paige-Green, P Date: Jul 2009 In addition to a number of other factors (social, economic, etc) sustainable transport requires the sustainable supply and use of construction materials. This includes the use of marginal materials, waste materials, novel / innovative materials ... 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
Moisture related test protocols for HVS testing

Author: Denneman, E ; Steyn, WJVDM ; Maina, JW ; Sadzik, ES Date: Oct 2008 In order to provide guidance on the possible methodologies for evaluating specifically moisture related pavement response using the Heavy Vehicle Simulator (HVS), this paper describes the objectives, potential effects and available methods ...
