Implementation of a performance-grade bitumen specification in South Africa

Abstract

Town in 1965, following which he was employed by the Provincial Government of the Cape Province as engineer in their Roads Department. From 1982 he was Chief Executive Officer of the Southern African Bitumen Association (SABITA) until his retirement in 2006. Since then he has acted as specialist consultant in pavement and materials engineering. He is a Fellow of the South African Institution of Civil Engineering, as well as of the Society for Asphalt Technology. His other interests include music and wildlife photography.

Flexible pavement performance and life cycle assessment incorporating climate change impacts

“…Changes in pavement design (Qiao et al, 2020) and asphalt material selection to meet the quality needed for future thermal and moisture conditions will be required (Practicò et al, 2011). For instance, better-performing asphalt surfacing layers could be achieved with bitumen modification (Sarroukh et al, 2021) and through specifying performance graded asphalt binders (Bredenhann et al, 2019;Mokoena et al, 2019), as currently being trialed in South Africa and internationally.…”

African Case Studies: Developing Pavement Temperature Maps for Performance-Graded Asphalt Bitumen Selection

“…Most countries in Africa still rely on empirical methods for bituminous binder classification in asphalt road construction. However, South Africa has recently moved towards the implementation of a performance-graded (PG) specification founded on principles of pavement performance [3].…”
