John & Jason presenting their findings
The event was well attended with a wide range of industry,
government and advisors
Held at the AAPA Offices in Eight Mile Plains, the UQ's Dr Kelly Johnstone and
researchers John and Jason presented the findings of their thesis project assessing the
exposure in the Queensland Asphalt sector to Respirable Crystalline Silica (RCS)

Following that the representatives of government, regulator, asphlat suppliers, profilers
and the broader industry reviewed the outcomes and considered the next steps.

Details of the Project, Outcomes & proposed Actions and RCS reference materials can
