Effective performance of bituminous binders in sprayed seals is a vital element in contributing to the overall performance of the sealed road network in Australia. To this end, Austroads has identified the maintenance of a minimum level of technical research capacity in bituminous surfacing as one of the four key research areas to be supported by Austroads as part of the Austroads Technology Program. To assist in defining research needs, a national workshop was proposed with the primary objective of defining performance requirements of sprayed seal binders through input from relevant stakeholders. A one day workshop was held at ARRB Group, Melbourne on Tuesday, 24 November 2009. Groups represented included state road authorities, local government, contractors, bituminous product suppliers and manufacturers, research organisations. Representatives from the stakeholder groups were invited to make a presentation that then became the basis for discussion in break-out groups and subsequently summarised as the priorities for referral to Austroads to be considered in the development of specific research projects.
