Advanced and automated laser-based technique to evaluate aggregates

Author: Anochie-Boateng, Joseph ; Komba, Julius J ; Mvelase, Gculisile M Date: Nov 2011 The Council for Scientific and Industrial Research (CSIR) is undertaking a research project to investigate the use of laser-based scanning technology to quantify the morphological/shape properties (i.e., form - flatness, elongation and ...

Effect of round particles on shear strength properties of railway ballast

Author: Mvelase, Gculisile M ; Anochie-Boateng, Joseph ; Msibi, LL Date: Jul 2016 The railway industry in South Africa is facing a problem where passage of trains on the heavy coal haul lines are causing degradation by means of wear (roundness) of ballast materials, and consequently, leading to differential track settlement ...

Investigation into flat and elongated particles ratio for asphalt mix design using a modern laser technique

Author: Anochie-Boateng, Joseph ; Mvelase, Gculisile M Date: Jul 2019 Flat and elongated particle ratio is a shape characteristic for coarse aggregates used in pavements. The ASTM D 4791 is the standard test method to determine flat and elongated coarse aggregate particles in asphalt mixes. However, this method ... Read more
Laboratory investigation on using coal ash as selected formation layer in a railway track substructure

Author: Mokoena, Refiloe ; Mvelase, Gculisile M Date: Oct 2019 The study presented in this paper aims to promote the use of coal ash in railway infrastructure as a more economical and sustainable material. The study serves as a preliminary investigation on using coal ash as one of the structural layers ... Read more
Sustainable pavement construction: Use of non-potable water and smart techniques for compaction

Author: Rampersad, Ashiel ; Mvelase, Gculisile M Date: Dec 2021 The western cape government reported an annual mean near-surface (2m) temperature (°C) change from the median and the 10% and 90% percentiles projected for 2036 – 2065 and 2066 – 2095. Across most of the country, model-simulated rainfall is ... Read more
Three-dimensional laser scanning technique to quantify aggregate and ballast shape properties

Author: Anochie-Boateng, Joseph ; Komba, Julius J ; Mvelase, Gculisile M Date: Jun 2013 There is a need to improve the measurements of shape characteristics of aggregates and ballast materials used in the construction of road, airfield, and railway track infrastructures. The fundamental shape properties of aggregate and ballast, ... Read more
The use of laser technology to investigate the effect of railway ballast roundness on shear strength

Author: Mvelase, Gculisile M ; Gräbe, PJ ; Anochie-Boateng, Joseph Date: Jun 2017 The heavy haul coal line of the South African railway network is facing a problem where ballast particles are becoming rounded, negatively affecting performance and thus leading to shorter planned maintenance cycles. This has been attributed ... Read more
Use of non-potable water in pavement construction: A laboratory study using seawater

Author: Rampersad, Ashiel ; Mvelase, Gculisile M Date: Jun 2021 The Intergovernmental Panel on Climate Change (2018) projects that global warming is likely to reach 1.5°C above pre-industrial levels between 2030 and 2052. The effect of climate change on warmer temperatures and longer lasting drought periods ... Read more
