  • Denneman, E; Verhaeghe, Benoit MJA; Sadzik, ES (Proceedings of the 26th Southern African Transport Conference 2007, 2007-07)
    The aggregate structure of the compacted mix is a determining factor for the performance of Hot-Mix Asphalt (HMA). In this paper, the grading characteristics of good and poor performing HMA mixes are explored using the ...
  • Kleyn, EG; Sadzik, ES; Rust, FC (1999-04)
    This paper describes the managerial approach and the process developed by the CSIR and the road authorities in managing the HVS projects and implementing the findings.The paper concludes with diagrammatic representation ...
  • Jooste, FJ; Kekwick, SV; Sadzik, ES; Rohde, GT (International Society for Asphalt Pavements (ISAP), 1997-08)
    The aim of this study was to investigate the following:how accelerated pavement testing predictions compare with actual road behaviour and performance the relative influences of load and environmental factors on pavement ...
  • Denneman, E; Steyn, WJVDM; Maina, JW; Sadzik, ES (2008-10)
    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 ...
  • Denneman, E; Sadzik, ES (2008-05)
    The discussion in this paper is based on the outcome of a detailed forensic investigation on the performance of Hot-Mix Asphalt (HMA) on five road sections in the Gauteng province. The investigation forms part of a larger ...
  • Denneman, E; Steyn, WJVDM; Maina, JW; Sadzik, ES (2008-10)
    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 ...
  • Denneman, E; Marais, H; Sadzik, ES (Southern African Transport Conference (SATC), 2008-07)
    The Marshall method is still the method of choice for the design of Hot-Mix Asphalt (HMA) in South Africa. During the validation of a HMA mix design, considerable variability was encountered in Marshall test results for ...
