21 August 2007   

This meeting covered the changes in Main Roads and the likely impact that
would have on the operations of the Alliance.  Of big interest was the crash at
Sippy Downs and the understanding of surface friction characteristics and
measurement of available and demand friction as represented in the courts.
Details were provided on the performance of binders at low temperatures, and
update on the status of specification revisions and development of performance
based specifications.  A district view of the asphalt specifications was and so
included.  Two workshops were held addressing a total of six questions.  
Responses to the questions and copies of the presentations are below:
