Spray seal stripping in the Wide Bay District
The final report from the Australian Road Research Board Group on spray seal stripping in Wide Bay District 2007 was delivered on 17 December 2007 and has confirmed the reasons provided by the department as to why the stripping occurred.
The report concludes that stripping occurred because of variations in the properties of the bituminous binder, resulting in variable adhesion between the binder and aggregate. With the combination of rain and record low temperatures that were experienced, the binder became increasingly brittle and traffic action stripped the aggregate from the surface. The full report is available for download below.
