  • Fostering child-centred approaches to transport research, planning and policy development : a pilot methodology 
    Mashiri, Mac; Dube, Sipho; Buiten, Denise (Unisa Press, 2007)
    Transport plays a significant role in the lives of children and young people, facilitating or constraining their ability to discharge their domestic responsibilities, providing opportunities for earning an income, ...
  • Ground stiffness measurement by the continuous surface wave test 
    Heymann, Gerhard (South African Institution of Civil Engineering, 2007-03)
    The continuous surface wave (CSW) test is a seismic technique for determining ground stiffness by measuring the velocity of Rayleigh wave propagation along the ground surface. A sinusoidal force is generated by a shaker ...

    Alexander, Will J.R.; Bailey, F.; Bredenkamp, D.B.; Van der Merwe, Alwyn; Willemse, Nico (South African Institution of Civil Engineering, 2007-06)
    This study is based on the numerical analysis of the properties of routinely observed hydrometeorological data which in South Africa alone is collected at a rate of more than half a million station days per year, with some ...
  • Forecasting household car ownership in South Africa : alternative models and future trends 
    Mokonyama, Mathetha; Venter, C.J. (Christoffel Jacobus) (South African Institution of Civil Engineering, 2007-09)
    The paper investigates the use of an alternative household car ownership modelling approach for South African urban areas, particularly the metropolitan areas, that moves away from existing race-based classifications, but ...
  • Effect of grinding time on the particle size distribution of gasification ash and Portland cement clinker 
    Du Plessis, Hanli; Kearsley, Elsabe P.; Matjie, Ratale Henry (South African Institution of Civil Engineering, 2007-12)
    In recent years the cement and concrete industry has reduced its environmental impact by increasing the use of waste materials as both cement extenders and fillers in concrete. Fly ash has been widely used as a cement ...
  • The performance of unpaved road material using soil stabilisers 
    Van Veelen, Martin; Visser, Alex T. (South African Institution of Civil Engineering, 2007-12)
    No abstract available
  • Finite element fracture modeling of concrete gravity dams 
    Cai, Qingbo; Robberts, John M.; Janse van Rensburg, Ben W. (South African Institution of Civil Engineering, 2008-03)
    A smeared crack model, based on non-linear fracture mechanics, was developed which allows for either linear or bilinear softening and assumes shear retention dependent on the strain normal to a crack. A mesh objectivity ...
  • Haul road defect identification using measured truck response 
    Hugo, D.; Heyns, P.S. (Philippus Stephanus); Thompson, R.J.; Visser, Alex T. (Elsevier, 2008-06)
    Current management techniques for the aintenance of mine haul roads, such as ad hoc blading, scheduled blading and even maintenance management systems, have shortcomings in complex mining environments. This paper investigates ...
  • Benchmarking the structural condition of flexible pavements with deflection bowl parameters 
    Horak, Emile (South African Institution of Civil Engineering, 2008-06)
    The falling weight deflectometer (FWD) is used worldwide as an established, valuable, nondestructive road testing device for pavement structural analyses. The FWD is used mostly for rehabilitation project level design ...
  • Destratification induced by bubble plumes as a means to reduce evaporation from open impoundments 
    Van Dijk, Marco; Van Vuuren, S.J. (Water Research Council, 2009)
    The use of thermal mixing by means of compressed air appears to have important potential for evaporation suppression on deep reservoirs. Current methods used to reduce evaporation from open-water impoundments such as ...
  • Track deflection measurement using particle image velocimetry 
    Grabe, Petrus Johannes (South African Institution of Civil Engineering, 2009-05)
    A new optical track deflection measurement device was developed for Transnet Freight Rail (Track Technology) to be used for track research carried out in both field and laboratory investigations. The functioning and ...
  • Mathematics vs pattern recognition in water resource studies 
    Alexander, Will J.R. (South African Institution of Civil Engineering, 2009-06)
    Pattern recognition is hard-wired into our brains. Unfortunately, it seems that most civil engineers have forgotten how to apply it to solve complex problems. This article gives some examples of where pattern recognition ...
  • Some lessons from Lagos 
    Venter, C.J. (Christoffel Jacobus) (South African Institution of Civil Engineering, 2009-09)
    In June 2009 the City of Tshwane's BRT Project Office hosted a World Bank-led workshop on public transport restructuring. A highlight was the presentations made by colleagues from Nigeria on their experiences with implementing ...
  • Potential applications of nanotechnology in pavement engineering 
    Steyn, Wynand Jacobus Van der Merwe (American Society of Civil Engineers, 2009-10)
    Nanotechnology is the term used to cover the design, construction and utilization of structures with at least one dimension measured in nanometers. Compared with typical civil engineering structures the two fields operate ...
  • Collapsible soils an overview 
    Rust, Eben; Heymann, Gerhard; Jones, Gary (South African Institution of Civil Engineering, 2010-04)
    Collapse potential in unsaturated soil was first identified and quantified by researchers in South Africa. A landmark paper was published by Ken Schwartz in 1985 presenting the state of the art at that time. Since then, ...
