Enrobé á Module Elevé (EME2) is the generic title for a high strength, long-life asphalt mixture that was developed in France. This report describes the second part of a study to assess the performance of EME2 mixtures and determine whether they need to be modified for use in Scotland. The in-service performance of EME2 materials used on three Scottish road network sites was assessed. Recommendations include investigating why the EME2 materials tested as part of this study produced significantly lower stiffnesses than EME2 materials produced in England. The study highlights the need to develop an analytical design method that incorporates fatigue performance and is not skewed towards materials with high stiffness. |
