High modulus asphalt (EME) technology transfer to South Africa and Australia: shared experiences

The paper describes experiences with the implementation of French enrobés à module élevé (EME) (high modulus asphalt) technology in South Africa and Australia. Tentative performance specifications for EME mixes were set in the two countries based on comparative testing using French, South African and Australian test methods. An overview of the development of the performance requirements from laboratory experiments is presented. Trial sections with EME technology were also constructed in both countries. Important findings from the field trials, in terms of mix design, manufacture and placement, and structural performance of EME are reported in the paper. The experiences with EME to date indicate that this stiff, rut and fatigue resistant asphalt technology provides real opportunities to build more sustainable and/or thinner asphalt pavements for heavy traffic loading situations. The analysis in this paper of the combined experimental work conducted in South Africa and Australia further support the specification limits for EME mix design.
