The AUSTROADS Pavement Research Group and the Australian Asphalt Pavement Association agreed to support an accelerated loading field trial using the accelerated loading facility (ALF) to determine if newly developed test equipment and procedures could produce asphalt mixes with improved resistance to rutting. An extensive laboratory evaluation program was also undertaken for comparison of the predicted results with those observed under ALF loading. The results of the field trial and the laboratory tests, and their relationship, are presented.
