Thermal-induced unilateral plate buckling of concrete pavements: design and evaluation. The project addresses the upheaval buckling of concrete pavements, which is caused by increasingly frequent heat spells. It will consider both the vulnerability assessment of existing pavements, and the design of new pavements made from low-carbon geopolymer concretes (which are lighter than conventional pavements) against upheaval buckling.

The Laboratory is aimed at developing and evaluating advanced traffic management and advanced vehicle technologies to improve the safety and efficiency of existing transport systems. The laboratory will comprise high-end computing and traffic simulation workstations with live real-time connections to a test-bed. The live link to the test-bed is a unique feature of the proposed facility. It will provide researchers with access to field data from sensors, videos and detectors to test prototypes of systems and evaluate their performance under live traffic conditions.Read moreRead less
Stabilisation of erodible and dispersive soils with natural wood processing by-products. Lignosulfonate is a by-product of paper and wood processing industry, which is an environmentally friendly organic compound with an immense potential for stabilising erodible and dispersive soils when mixed in small quantities. This project will deliver practical design guidelines and specifications for sustainable performance of road and rail embankments that are treated with lignosulfonates.

Lignosulfonate is a by-product of paper and wood processing industry, which is an environmentally friendly organic compound with an immense potential for stabilising erodible and dispersive soils when mixed in small quantities. This project will deliver practical design guidelines and specifications for sustainable performance of road and rail embankments that are treated with lignosulfonates. Utilisation of lignosulfonates in soil stabilisation is not only cost-effective, but also has the benefit of eliminating a waste disposal problem. The proposed project will improve industrial competitiveness and Australia's export earnings through increased commercialisation and technology transfer in the region.Read moreRead less
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
Assessment and Prediction of Particle Breakage under Cyclic Loading. Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation. Simulation of particle breakage subject to cyclic loading is pioneering fundamental research that wi ....Assessment and Prediction of Particle Breakage under Cyclic Loading. Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation. Simulation of particle breakage subject to cyclic loading is pioneering fundamental research that will have significant impact on the design and maintenance of future rail and road networks. A full understanding of the breakage mechanisms of aggregates will lead to innovative techniques in design and construction, including faster trains carrying heavier loads with reduced maintenance costs.Read moreRead less
The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, an ....The effect of tunelling on existing rock bolts. As more underground facilities such as rail, road, sewerage and service tunnels are constructed in our major cities, more and more frequently new tunnels have to cross over or run alongside existing tunnels. As the roofs of tunnels are generally supported by rock bolts and lined with shotcrete, the support system can be damaged by the rock movements caused by the excavation of the new tunnel. Little research has been carried out on this problem, and so often expensive deviations have to be made to tunnels to avoid going near existing ones. The proposed research will provide numerical tools to allow prediction of loads induced into rock bolts by nearby tunnels, leading to more economical and safer tunnel design.

Enhanced Analysis of Time Dependent Viscous Behaviour of Soft Clay. Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects.

Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects. The community can considerably benefit from the findings of this project including safer structures, significant reduction in the future maintenance costs and enhancing the performance of bridges, buildings, roads, railways and dams with less cracks and differential settlement.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

High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards.

Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators will apply their extensive knowledge in thin-walled tubular structures to establish the most economical means of designing high strength bollards. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less
