In 2006, John led the Australian asphalt study tour to the US and also in 2007 to Europe and South Africa.
John represented RMS as a member of the Austroads Asphalt Research Reference Group.
John has international exposure and is often invited to present at conferences and events.
John is well known by his peers for his passion for pavements and has been a key player in the flexible pavement industry towards the implementation of the following technologies:
All the above technologies were implemented with zero failure rate. This was achieved through partnering with the pavements industry.
In 2014, John led a study tour to Belgium concentrating on continuously reinforced concrete roundabouts. Belgium is a leader in CRCP in roundabouts. Based on his strong relationships with professionals in Belgium, John has introduced and adapted this technology to Australian conditions.
In 2016, John visited Texas Department of Transportation to capture the latest design and construction practice on continuously reinforced concrete pavements (CRCP). During his visit in Texas, John arranged technology transfer sessions with international experts on world’s best practice on CRCP technology. Also, during this visit, John arranged a technology transfer session with Tencate on the use of geosynthetics with enhanced lateral drainage capabilities in roadway systems. Since then, John has expanded his knowledge and experience in the use of geogrids for ground stabilisation.
In 2018, John visited Georgia Department of Transportation to discuss asphalt technology topics including stone mastic asphalt, porous asphalt mixes and microsurfacing. During this visit, John attended the 1st International Conference on Stone Matrix Asphalt in Atlanta. Also, during this visit, John arranged a technology transfer session with Tensar International Corporation where he was introduced to the latest technology on mechanical stabilisation incorporating stiff geogrids into unbound road base layers to improve the mechanical properties of the layer with a resulting improvement in pavement performance.
Since 2019 John has been assisting Tensar International (UK) with technical support and in the development of pavement notes on mechanical stabilisation. John regularly delivers webinars through Tensar Australia & NZ promoting the performance benefits of mechanical stabilisation.
