EME2
EME2 (Enrobé à Module Élevé Class 2) is a high-modulus binder specifically designed for use in deep-lift structural asphalt layers. Originating in France and now adopted in Australia under Austroads and TMR specifications, EME2 enables thinner, stronger pavements capable of handling high traffic and loading.
By significantly increasing asphalt stiffness, EME2 allows pavement thickness reductions of approximately 25–33%, delivering long-term cost savings without compromising structural integrity.
EME2 mixes are produced with a high binder content (around 6%), providing excellent rut resistance and stability. Due to their increased stiffness and brittleness, EME2 binders are used exclusively in base or sub-base layers, where tensile strains are low and fatigue is not the controlling design factor.
Key Features of EME2:
-
📏 Reduces pavement thickness by 25–33% compared to conventional asphalt
-
🔩 High modulus for superior stiffness and structural support
-
🚛 Exceptional rut resistance, ideal for heavy traffic and freight routes
-
🧱 Used only in structural layers (not surfacing) due to its brittle nature
-
🧪 Designed for high binder content (~6%) in accordance with Austroads mix design protocols
EME2 is a specialised solution for projects seeking efficient structural design, especially where long-haul traffic, freight demands, or axle loading make deformation resistance a priority.
