Topic 2: High performance asphalt & bindersOverview of reasons• Bituminous binders − key component in the performance andservice life of bituminous surfacings & asphalt pavements• About 90% of the Australian all weather road network length issurfaced with sprayed seals − about 50% of binder usage• Need to ensure optimum asphalt and seals performance in thefield, and to promote best practices suitable to be adapted andadopted in Australia. Seeking details on:o new developments and test methods in high performance asphalt andbituminous materials (e.g. HiMA /EME, PMB, Emulsion)o actions taken by European and others (e.g. binder manufacturers,asphalt producers and researchers) to overcome field problems (e.g.climate change)o correlation between laboratory test results and field trialsAAPA 2012 Study Tour to Europe – High performance asphalt and bindersPart 1 v1www.aapa.asn.au
