Joe Grobler’s specialty includes initial and detailed pavement assessments.
DR. JAMES GRENFELL, SENIOR TECHNICAL LEADER, AUSTRALIAN ROAD RESEARCH BOARD Since joining ARRB in February 2017 Dr. Grenfell has focussed on current Austroads projects by looking at improving knowledge of foamed bitumen stabilised pavements and the use of lightly bound pavement materials in pavement construction. In particular, Dr. Grenfell will cover Austroads project TT2046 – improving the cost effectiveness of foamed bitumen stabilised pavements. The project aims to provide an improved understanding of the performance of foamed bitumen stabilised (FBS) pavements through full-scale
accelerated pavement testing. One half of this project is to assess the fatigue performance of these foamed bitumen stabilised pavements under Accredited Loading Facility (ALF). Three test strips comprising of a 100 per cent granite host material, a 50 per cent granite – 50 per cent Reclaimed Asphalt Pavement (RAP) lane and an 80 per cent previously cement treated – 20 per cent granite material, each stabilised with 3 per cent foamed bitumen and 2 per cent hydrated lime are being assessed. The three test strips have been constructed and are being subjected to accelerated loading using ALF. Initial pavement loading was undertaken using an ALF load of 40 Kilonewtons (kN).
