Abstract:
This technical paper explores the concept of perpetual pavements and its applicability in
Southern Africa. Beginning with a historical overview of the development of perpetual
pavements, the paper examines their successful application in America, Europe, and other
regions. The focus then shifts to the potential implementation of perpetual pavements in
Southern Africa, considering regional factors and proposing typical concept pavements
suited to the unique challenges and conditions of the area. Based on the insights
gathered, recommendations for the implementation of perpetual pavements in Southern
Africa include the use of Enrobé à Module Élevée (EME) asphalt as a base layer with
either a granular or cemented subbase supporting layer, optimized to ensure initial
pavement failure is located in the surfacing layer. Emerging technologies, such as
advanced asphalt mix formulations and nano technology, have the potential to further
enhance the performance and sustainability of perpetual pavements.
