Evaluation of EME transfer functions and critical layer thicknesses

The initial document for design of Enrobé à Module Élevé (EME) in South Africa was published based on the French EME technology. This document covers the mix design while it recommends a mechanistic approach to determine the required layer thicknesses and structural configuration of the pavement. Various aspects of the EME technology has been evaluated in South Africa since introduction of this first design document, and improvements are due regarding the initial fatigue and rutting transfer functions as well as in the general understanding of the behaviour of these layers in pavement structures. In this paper, the improved transfer functions are presented, and analyses on the optimal thickness requirements for different traffic scenarios are discussed. The outcome of these analyses (partly based on laboratory testing of EME samples and partly based on in situ measurements of pavement responses) are presented and discussed to further the local understanding of the benefits and limitations of EME technology.
