    Guided wave based monitoring systems require accurate knowledge of mode propagation characteristics such as wavenumber and group velocity dispersion curves. These characteristics may be computed numerically for a rail ...
  • Rust, FC; Akhalwaya, Imraan; Jordaan, GJ; Du Plessis, L (2019-10)
    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 ...
  • Walubita, LF; Mahmoud, E; Lee, SI; Carrasco, G; Komba, Julius J; Fuentes, L; Nyamuhokya, TP (Elsevier, 2019-07)
    One of the common methods to mitigate reflective cracking, in existing cracked pavements, is the use of interlayer grid reinforcements in hot-mix asphalt (HMA) overlay construction during maintenance and/or rehabilitation ...
  • Adedeji, KB; Hamam, Y; Abu-Mahfouz, Adnan MI (2019)
    Increasing water demand due to urbanization creates a need to develop schemes for managing water supply networks (WSNs). In recent years, hydraulic modeling of WSNs has been used to assess the state of networks in terms ...
  • Bello, O; Abu-Mahfouz, Adnan MI; Haman, Y; Page, Philip R; Adedeji, KB; Piller, O (MDPI, 2019-03)
    Modern water distribution networks (WDNs) are complex and difficult to manage due to increased level of urbanization, varying consumer demands, ageing infrastructure, operational costs, and inadequate water resources. The ...
  • Abu-Mahfouz, Adnan MI; Hamam, Y; Page, Philip R; Adedeji, KB; Anele, AO; Todini, E (MDPI, 2019-03)
    The impact of climate change and increasing urbanisation throughout the world has forced water utility managers to increase the efficiency of water resources. Reduction of real (or physical) water losses plays a crucial ...
  • Steenkamp, AJ; Berman, Robert B; Kemp, Lana; De Saxe, Christopher C (Southern African Transport Conference, 2019-07)
    The paved road network is a critical asset to any economy. South Africa has a paved road network that has an estimated value in excess of R2 trillion. This asset is however under threat as there was a backlog in maintenance ...
  • Cooper, Antony K (University of Pretoria, 1993-06)
    The purpose of this dissertation is to assess digital geo-referenced information and standards for exchanging such information, especially the South African National Exchange Standard (NES). The process of setting up a ...
  • Sinvula, KM; Coetzee, S; Cooper, Antony K; Hipondoka, M (2012-10)
    During the 1990s Namibia marked the introduction and acceptance of desktop Geographical Information System (GIS) technology into various sectors at national, regional and local community levels. This technology quickly ...
  • Cooper, Antony K; Peled, A (International Cartographic Association, 2001-08)
    A user of geographical data invariably compiles their data base using core data sets obtained from various sources. They then integrate these together to meet their particular needs and build their own, value-added data ...
  • Komba, Julius J; Maina, JW; Horak, E; Steyn, W (ASCE, 2019-07)
    Compaction of Hot-Mix Asphalt (HMA) is an essential process in the construction of asphalt pavement as it is critical to the performance of the road infrastructure. The compaction process enables the asphalt mixtures to ...
  • Le Roux, Alize; Khuluse-Makhanya, Sibusisiwe; Arnold, Kathryn A; Engelbrecht, Francois; Paige-Green, P; Verhaeghe, Benoit M (Elsevier, 2019-08)
    African communities are worst affected by climate-related natural disasters, in part due to high socio-economic vulnerability, natural resource dependency and low adaptive capacity. Climate resilient road infrastructure ...
  • De Saxe, Christopher; Berman, Robert J; Clarke, Anria; Reinecke, John D (2019-07)
    Tyre parameterisation is fundamental to vehicle dynamics research, as tyre properties have a significant impact on the behaviour of a vehicle. One way in which some of the primary tyre parameters can be extracted is a ...
  • Cooper, Antony K; Coetzee, S; Rapant, P; Iwaniak, A; Hjelmager, J; Moellering, H; Huet, M; Sinvula, K (Copernicus Publications, 2019-07)
