High modulus asphalt mix (EME) for heavy duty applications and preliminary laboratory test results in Australia

With the ever increasing traffic intensity and axle loadings, the state road authorities and the road construction industry face the challenge of designing and delivering high performance asphalt materials to meet the increasing demands. As part of Austroads project TT1353, ‘Asphalt properties and mix design procedures’ ARRB conducted a study in 2012/2013 to investigate the potential introduction of the French high modulus hot mix asphalt technology, called enrobes a module eleve (EME) to Australia. The EME mix technology provides a high performing asphalt material for use in heavy duty pavements, specifically suitable to carry large volumes of heavy vehicles, where there is a need for increased resistance to permanent deformation. Also, the technology can be utilised successfully in pavement strengthening, especially in areas with clearance constrains. By using locally available aggregates and hard penetration grade bitumen, a laboratory based demonstration project, strictly based on performance related testing, was performed to provide insight and guidance for EME mix design. The laboratory program carried out in the work included the comprehensive characterisation of the EME mix on performance related testing, such as workability, durability, rutting resistance, stiffness and fatigue resistance. In France, EME is designed and tested according to the European test series EN 12697, and specification requirements are set according to these test methods. The need for identifying specification limits based on locally available test methods is highlighted in the work, which needs to be completed in future research for a successful introduction of the technology to Australia.
