The ARC Research Hub for Smart Next Generation Transport Pavements aims to make road, airport and dockyard pavements smart, low cost, long-lasting, safe, green and adaptable to future transport demands. Australia’s road network, upon which the nation depends for its economic and social prosperity, is at risk due to increases in passenger and freight load degradation of the road network, and material and expertise scarcity. The Hub will deliver new materials and modelling, smart construction, and rehabilitation systems required for future demands, while enhancing road safety and reducing environmental impact.

Motorway management system integrating safety, efficiency & sustainability. This project aims to develop a motorway management system that holistically optimises motorway safety, efficiency, and sustainability via intervening the traffic flow dynamics. In the current practice of motorway traffic flow management, safety, efficiency, and sustainability are fundamentally connected but separately managed as they are modeled by distinct methodologies. The new system is based on a proposed traffic flo ....Motorway management system integrating safety, efficiency & sustainability. This project aims to develop a motorway management system that holistically optimises motorway safety, efficiency, and sustainability via intervening the traffic flow dynamics. In the current practice of motorway traffic flow management, safety, efficiency, and sustainability are fundamentally connected but separately managed as they are modeled by distinct methodologies. The new system is based on a proposed traffic flow theory which includes a microscopic model for safety analysis and a derived macroscopic model for efficiency and sustainability analysis. This theory can be used to resolve the above-mentioned long unsettled challenge and significantly improve our motorway performance.Read moreRead less
Containment and Reduction of Rework in Transport Mega Projects. Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced. Having to perform rework has been identified as a major factor that contributes to these unintended consequences. As there has been limited research that has empirically examined rework causation, an inability to develop effective rework containment and red ....Containment and Reduction of Rework in Transport Mega Projects. Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced. Having to perform rework has been identified as a major factor that contributes to these unintended consequences. As there has been limited research that has empirically examined rework causation, an inability to develop effective rework containment and reduction strategies prevails. This research aims to develop a theoretical model that can be used to develop robust containment and reduction strategies to mitigate the adverse economic, productivity and safety consequences that materialize from performing rework during the construction of mega transport projects.Read moreRead less
Advancement of Vacuum Pressure Application via Prefabricated Vertical Drains for Stabilising Soft Ground. Coastal Australia is under ever increasing pressure from rapid population growth which requires continual capital investment in civil infrastructure, such as road and rail links and large buildings.

Coastal Australia is under ever increasing pressure from rapid population growth which requires continual capital investment in civil infrastructure, such as road and rail links and large buildings. Many regions have soft compressible clays that present challenges for infrastructure design and construction. The use of vacuum preloading, together with vertical drains for soft soil stabilisation, can reduce construction and maintenance costs, while the increased soil strength will enhance the stability of infrastructure. This project will deliver design guidelines and specifications of enhanced vacuum consolidation application, as well as improving industrial competitiveness and export earnings through increased technology transfer.Read moreRead less
Effectiveness of prefabricated vertical band drains (PVD) in the stabilisation os soft clays. Stabilisation of structures in low-lying coastal Australia is affected by excessive settlement, low bearing capacity, and high lateral displacement of soft clays upon loading. The use of prefabricated vertical drains (PVD) prior to main construction can ensure pre-compression of soft clays by rapid pore water pressure dissipation, thereby increasing the soil strength and minimising its post construction ....Effectiveness of prefabricated vertical band drains (PVD) in the stabilisation os soft clays. Stabilisation of structures in low-lying coastal Australia is affected by excessive settlement, low bearing capacity, and high lateral displacement of soft clays upon loading. The use of prefabricated vertical drains (PVD) prior to main construction can ensure pre-compression of soft clays by rapid pore water pressure dissipation, thereby increasing the soil strength and minimising its post construction deformation. The main goal is to fully understand the stabilising mechanisms of PVD in soft clay, and to minimise the unfavourable effects of soil disturbances (smear) during installation. Extensive laboratory and field studies plus computer modelling will result in innovative design concepts and enhanced construction practices.Read moreRead less

Government and industry are increasing truck masses from current single articulated 42.5 tonne trucks to 160 tonne multi-bogie trucks. This will provide Australia with over $1 billion of potential benefits and an efficient and competitive transport industry. To capture these benefits and further progress Australia's economy, considerable collaborative research on a number of fronts must be carried out investigating how bridges and barriers can perform safely when subjected to very heavy traffic and impact loads under laboratory and typical service conditions. This application seeks funds for establishing a unique hi-tech testing facility in Australia vital for advancing such infrastructure technology.Read moreRead less
Development of a novel mobile sensory system for bridge health monitoring. The aim of this project is to provide accurate, rapid and cost-effective ‘health checks’ for bridges.

Transportation infrastructures are subject to continuous degradation due to the environment, ageing and excess loading. This project plans to develop a vehicle equipped with sensors as a mobile sensing platform to catch the dynamic interaction between the vehicle and the bridge. The interaction information would be used to assess the health of the bridge infrastructure through substructuring techniques. The expected output of this project would enable managers to monitor the structural conditions and provide an economical infrastructure asset management scheme to protect the structure and human lives.Read moreRead less
Performance of Soft Clay Consolidated by Biodegradable and Geosynthetic Vertical Drains under Vacuum Pressure for Transport Infrastructure. Along Australia's coast, the abundance of soft clay often hampers the design and construction of transport infrastructure including embankments. The use of vacuum pressure and prefabricated vertical drains (PVD) ensures rapid drainage and consolidation of the clay, thus increasing its shear strength and bearing capacity while reducing long term deformation. ....Performance of Soft Clay Consolidated by Biodegradable and Geosynthetic Vertical Drains under Vacuum Pressure for Transport Infrastructure. Along Australia's coast, the abundance of soft clay often hampers the design and construction of transport infrastructure including embankments. The use of vacuum pressure and prefabricated vertical drains (PVD) ensures rapid drainage and consolidation of the clay, thus increasing its shear strength and bearing capacity while reducing long term deformation. The main aim of this project is to achieve technological advancement in sustainable and cost effective PVD-vacuum systems by minimising the time to achieve the desired degree of consolidation, thereby controlling post construction settlement and lateral movement. Extensive laboratory and field studies supported by numerical modelling aim to result in new industry guides and standards.Read moreRead less
