SPARC Hub is leading the effort to address the current key issues in unbound granular material testing, design and construction processes and make further advancements to maximise the benefits of increasing digitalisation within the so-called Industry 4.0 revolution. The Hub is organising a two-day online symposium on unbound flexible pavements in September 2022 targeting primarily the Australian construction industry. The symposium comprises a range of keynote speeches from world-renowned experts in various countries and panel discussions with industry experts and leaders with a view to advance the current approach for testing, design and construction of unbound flexible pavements.
