This project aims to advance fundamental knowledge on the complex behaviour of reactive soils in the context of resilient geotechnical infrastructure. This research falls within the research priority “Environmental Change”, as geotechnical infrastructure need to sustain the impact of ever more frequent and more intense climatic actions. Attention will focus on the effect of suction on volume change and shear strength of reactive soils, two poorly understood features, and will produce a swelling model and a soil-deformable structure interaction model. After validation by a case study, the models will have the potential to empower industry to produce geotechnical infrastructure that can better sustain climatic actions.Read moreRead less

This project aims to develop the mechanics of geosynthetic-reinforced flexible pavements as an urgent need for the Australian pavement industry to build more sustainable and economical roads. Novel laboratory test apparatus and in-situ test programs, and mathematical models will be developed, for the first time, to capture the responses of reinforced base courses in a complete and optimised way to determine the parameters for pavement design and performance evaluation. The outcomes will enable reliable prediction of reinforced pavement behaviour, leading to better-performing geosynthetic products and more resilient pavements, reduced material usage and damage in pavements, and less environmental impact and maintenance cost.Read moreRead less
A novel design approach for sustainable and resilient railway formations. The project aims to validate a novel design approach for more sustainable and resilient railway formations.

The project aims to validate a novel design approach for more sustainable and resilient railway formations. The railway network underpins the Australian economy and its maintenance costs tens of millions of dollars every year. This cost will increase with the growing frequency and intensity of climatic events. The research will advance the knowledge on the effect of water on the performance of railway formations and will deliver a novel design tool for end-users that will allow engineers to recycle fouled ballast in formations . The project will yield significant financial benefits for Australia, will strengthen links between Academia and industry partners, and will address environmental and sustainability issues linked to fouled ballast.

Carbon-negative concrete produced with innovative artificial aggregates. To achieve net-zero carbon emissions in Australia by 2050, this project proposes to develop carbon-negative concrete using two typical industrial wastes, recycled powder from construction and demolition waste and drinking water treatment sludge from the water industry. This project first aims to develop innovative artificial aggregates containing sludge-derived biochar and recycled powder under carbonation curing.

To achieve net-zero carbon emissions in Australia by 2050, this project proposes to develop carbon-negative concrete using two typical industrial wastes, recycled powder from construction and demolition waste and drinking water treatment sludge from the water industry. This project first aims to develop innovative artificial aggregates containing sludge-derived biochar and recycled powder under carbonation curing. The developed artificial aggregates with superior carbon absorption capacity are then used to produce carbon-negative concrete. The properties of artificial aggregates and carbon-negative concrete will be comprehensively investigated. This project creates a green engineering solution to stockpiled industrial wastes.

Creating pH-sensitive self-healing concrete using sludge waste for sewers. In Australia, our 117,000 km of concrete sewer pipes are currently internally corroding at a depth rate of 1-3 mm per annum. The repair of deteriorated concrete is costly and often short-lived. Based on an advanced composite technology, this project will develop a pH-sensitive self-healing concrete that can repair itself without human intervention at the early stage of corrosion. Sludge waste from drinking water treatment ....Creating pH-sensitive self-healing concrete using sludge waste for sewers. In Australia, our 117,000 km of concrete sewer pipes are currently internally corroding at a depth rate of 1-3 mm per annum. The repair of deteriorated concrete is costly and often short-lived. Based on an advanced composite technology, this project will develop a pH-sensitive self-healing concrete that can repair itself without human intervention at the early stage of corrosion. Sludge waste from drinking water treatment will be utilised as a healing agent to mitigate the corrosion. Combined experiments and molecular dynamics simulation will uncover all aspects of the healing process to enable the practical application of this technology. The findings will extend the lifetime of concrete structures and promote a circular economy.Read moreRead less
Reducing geotechnical design conservatism to secure floating wind energy. The next frontier for offshore wind energy is moving further out to sea to avail of stronger and more consistent wind speeds. In these water depths, wind turbines are installed on floaters tethered to anchors in the seabed. Geotechnical design of anchors is inherently conservative, having been shaped by technical and economic considerations of oil and gas facilities. The offshore wind energy industry cannot afford to adopt ....Reducing geotechnical design conservatism to secure floating wind energy. The next frontier for offshore wind energy is moving further out to sea to avail of stronger and more consistent wind speeds. In these water depths, wind turbines are installed on floaters tethered to anchors in the seabed. Geotechnical design of anchors is inherently conservative, having been shaped by technical and economic considerations of oil and gas facilities. The offshore wind energy industry cannot afford to adopt such conservatism if floating wind is to become commercially viable. This project will, through numerical developments, geotechnical centrifuge modelling and field testing, develop the science that will lead to a reliability-based geotechnical design approach to make floating offshore wind energy economic and viable.Read moreRead less

Mud pumping under rail tracks is identified as the most frequent issue causing the degradation of rail tracks and increasing their ongoing maintenance cost across Australia and worldwide. This project aims to further the understanding of mud pumping mechanisms across different scales. A novel combined experiment-computational approach will be developed to observe, analyse and link different material properties and external conditions governing the mud pumping process. It will lead to better criteria for mud pumping and numerical tools for field scale failure analysis and risk assessments. The expected outcomes include the enhanced capability to assess the integrity and stability of rail tracks and better design criteria against mud pumping.Read moreRead less

This project aims to hydraulically calm WDNs to improve their performance, informed by smart sensors. The project will generate insightful knowledge of the hydraulic behaviour of real WDNs. The outcomes will be new strategies to identify, eliminate and suppress harmful pressure perturbations, leading to a reduced burst rate, extended asset life, improved system operation and advanced design principles. The resultant sustainable water assets provide significant economic and environmental benefits to the water industry and society.Read moreRead less
