Asphalt rutting and its prevention

Author: Verhaeghe, Benoit MJA ; Myburgh, PA ; Denneman, E Date: Sep 2007 The paper seeks to redress the concerns expressed at the eight Conference on Asphalt pavements for Southern Africa (CAPSA) that the design of hot-mix asphalt did not adequately address prevention of rutting. It presents a consolidation of ... Read more
Bitumen rubber asphalt mix testing for South African pavement design method

Author: Anochie-Boateng, Joseph ; Denneman, E ; Verhaeghe, Benoit MJA Date: Jul 2011 The South Africa National Road Agency Ltd has entered into a research and laboratory testing agreement with the CSIR to support the revision of the South African Pavement Design Method (SAPDM). The research includes characterising a bitumen-rubber ... Read more
Caltrans accelerated pavement testing (CAL/APT) program - test results: 1993-1996

Author: Nokes, WA ; Harvey, JT ; Du Plessis, L ; Long, F ; Stolarski, PJ Date: Aug 1997 By combining the results of both the HVS and laboratory tests, interpretations of pavement performance are described and recommendations for pavement design and construction have been made to Caltrans. Read more
Comparison between the permanent deformation behaviour of a standard and a rut resistant HMA (hot-mix asphalt) mix

Author: Steyn, WJvdM ; Denneman, E ; Mahlangu, S Date: Jul 2008 In this paper the focus is on the comparison between the permanent deformation behaviour of the standard HMA mix and one rut resistant HMA mix of which the grading differs from that of the standard HMA mix. The permanent deformation has been ... Read more
Evaluation of deformation response of HMA under APT and wheel tracking tests

Author: Denneman, E ; Steyn, WJVDM ; Maina, JW ; Sadzik, ES Date: Oct 2008 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 acceptance criteria for ... Read more
Laboratory performance and modelling behaviour of hot-mix asphalt with recycled crushed glass

Author: George, Theresa B ; Anochie-Boateng, Joseph ; Jenkins, KJ Date: Sep 2020 In South Africa research is currently under way to determine the suitability of using locally available recycled crushed glass as a partial fine aggregate substitute in the production of asphalt mixes. This paper characterises the laboratory ... Read more
Permanent deformation and in-depth deflection records for selected HVS tests

Author: Theyse, HL Date: Mar 1999 Transportek has been involved in accelerated pavement testing (APT) with a fleet of Heavy Vehicle Simulators (HVSs) over the past two decades. During this period, a vast amount of pavement response and performance data has been accumulated, ... Read more
Permanent deformation behavior of naturally occurring bituminous sands

Author: Anochie-Boateng, Joseph ; Tutumluer, E ; Carpenter, SH Date: 2008 Oil sand, or tar sand, is a generic name given to bituminous sand deposits that are rich in bitumen or asphalt content to the extent that oil can be extracted from these deposits. The typical 8% to 15% presence of bitumen in the soil composition ... Read more
Permanent deformation testing for a new South African mechanistic pavement design method

Author: Anochie-Boateng, Joseph ; Maina, J Date: Jan 2012 The South Africa National Road Agency Limited together with the CSIR are undertaking a research and development project to support the revision of the South African mechanistic-empirical pavement design method. An important part of this project ... Read more
A study of the influence of coarse aggregate shape characteristics on permanent deformation of asphalt mixes

Author: Mabuse, MM ; Anochie-Boateng, Joseph ; Komba, Julius J ; Ndambuki, JM Date: Jul 2013 The effect of aggregate shape properties such as angularity, texture, sphericity, roundness, flat and elongation on the performance of asphalt mixes have not been thoroughly investigated using direct measurement techniques. This is partly ... Read more
Sustainable use of oil sands for geotechnical construction and road building

Author: Anochie-Boateng, Joseph ; Tutumluer, E Date: Feb 2012 Oil sands are natural deposits of bituminous sand materials that are mined and processed for crude oil. They are routinely used in oil sand fields for building temporary and sometimes permanent roads serving mining and hauling activities. ... Read more
