Evaluation of the use of polymer modified bitumen in the production of high modulus asphalt for heavily-trafficked roads

Author: Komba, Julius J ; Verhaeghe, Benoit MJA ; O'Connell, Johannes S ; Anochie-Boateng, Joseph ; Nortje, W Date: May 2015 Enrobé à Module Élevé (EME) technology, a High Modulus Asphalt (HiMA), has been introduced to South Africa to provide an optimum solution for the design and construction of heavily trafficked roads. Implementation of EME technology in South ... Read more
Forensic investigation into the performance of hot-mix asphalt

Author: Denneman, E ; Sadzik, ES Date: May 2008 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 project to improve ... Read more
Method to determine full work of fracture from disk shaped compact tension tests on hot-mix asphalt

Author: Denneman, E Date: Aug 2010 Fatigue cracking is an important mode of failure in hot-mix asphalt (HMA). As part of the revision of the South African pavement design method (SAPDM) a need was identified to assess the fracture toughness of HMA in terms of fracture energy. ... Read more
