Current Austroads Guides indirectly specify that asphalt pavements in Queensland must be thicker than those in other Australian states owing to the prevailing environmental and traffic conditions. The incorporation of high modulus asphalt layers would increase overall pavement stiffness, at the same time maintaining the same structural performance. In this project the pavement structural design using the French class 2 high modulus asphalt (Enrobé à Module Élevé – EME2) is discussed. The EME2 concept significantly differs from the way dense graded asphalt is currently modelled in Australia.
