Hot-mix asphalt testing for the South African pavement design method

Author: Anochie-Boateng, Joseph ; Denneman, E ; O'Connell, Johannes S ; Mturi, George AJ ; Ventura, D Date: Aug 2010 As part of the revision of the South African Pavement Design Method (SAPDM), a large scale field and laboratory study into the material response of asphalt mixtures will be undertaken. A first step in this process is to review the state-of-the ... Read more
Improved performance evaluation of road pavements by using measured tyre loading

Author: Maina, JW ; De Beer, Morris Date: Nov 2008 This paper presents evaluation of road pavement response under the loading of typical dual and single truck tyre configurations. Locally developed Stress-In-Motion (SIM) technology was used to quantify three-dimensional (3D) shapes of the ... Read more
An investigation of aggregate degradation in a high stress field

Author: Mgangira, Martin B ; Xungu, Sipho A ; Giani, John C Date: Jul 2018 The deterioration of the aggregate material used in road construction is of concern as it affects the overall long term stability of the road pavement and should be minimised by using durable aggregates. The paper presents proof of concept ... Read more
Laser-based approach for determining flakiness index of aggregates used in pavements

Author: Anochie-Boateng, Joseph ; Komba, Julius J ; O'Connell, Johannes S Date: Jul 2011 There are concerns about the standard methods/procedures for quantifying shape properties of rock aggregates used in road and airfield pavements. The CSIR has recently acquired a portable three-dimensional (3D) laser scanning device to address ... Read more
Using tire road contact stresses in road pavement design and analysis

Author: De Beer, Morris ; Maina, JW Date: 2011 Simple tire-pavement contact analysis reveals that higher contact stresses from truck tires could result in increased potential for road pavement failures. Read more
