Austroads: Transport Research and Trends
Government
Flexible granular pavements protected by sprayed seal surfacings are the backbone of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have therefore been focused on producing quality, long-lasting sprayed seal surfacings. Such efforts include conducting research into bituminous binders as a key component of sprayed seals.
A landmark achievement in this area was the Austroads sprayed seal trial sites at Coober Pedy in South Australia and Cooma in New South Wales. These trials were established to evaluate the relative performance of seals constructed using various grades of binders, from their placement through to long-term service. This was a significant research investment made to ensure that the national specifications and test methods that are used for the procurement of sealing binders are contemporary and robust, and incorporate performance requirements to ensure that the bituminous binders that are being procured are of suitable quality and are not prone to premature ageing.
This webinar presents the outcomes of the Austroads research project which was conducted to monitor the performance of the trial sites up to about 8 years since construction. The project work includes comprehensive studies on the ageing properties of trial binders and their effects on the life of sprayed seal surfacings.
Presented by Young Choi and Steve Patrick.
