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.

Development of next generation fire-resistant composite columns. This project aims to develop a new generation of concrete-filled steel tubular (CFST) columns free from reinforcement by using fly ash-based fire-resistant concrete. In Australia, existing CFST columns use a large amount of internal reinforcement to maintain the structural integrity under fire attack.

Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechani ....Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechanisms of mud pumping, incorporating train loads and frequencies, will be studied, and the role of vertically installed drains will be quantified for improved practical design. The project aims to contribute to improved track longevity and reduced maintenance costs, with a corresponding boost in rail productivity.Read moreRead less
A novel method to stabilise expansive soils by alkali-activation . This project aims to address durability and sustainability issues with traditional lime-based methods used to stabilize expansive soils by alternatively advancing an alkali-activation approach. It expects to generate new knowledge in using alkali-activation to suppress the swelling potential of expansive soils which have been deleterious to roads, pavements and overlying structures.

This project aims to address durability and sustainability issues with traditional lime-based methods used to stabilize expansive soils by alternatively advancing an alkali-activation approach. It expects to generate new knowledge in using alkali-activation to suppress the swelling potential of expansive soils which have been deleterious to roads, pavements and overlying structures. Expected outcomes of this project include development of a long-term durable treatment with reduced carbon footprint and use of waste materials. This should provide significant benefits commercially and critical insights to overcome expansive soils which cover approximately one-fifth of Australia’s surface area and six out of eight of its largest cities.Read moreRead less
Geotechnical properties and compaction characteristics of granular wastes as potential port reclamation fill. In moving towards sustainable waste management, the Australian mining and steel industry is proactively seeking large scale recycling schemes for coal wash and slag. If the construction potential of these wastes is favourable for reclamation, then the environmental and socio-economic benefits will be substantial due to less quarrying of fresh rock and reduced volume of waste tips on oth ....Geotechnical properties and compaction characteristics of granular wastes as potential port reclamation fill. In moving towards sustainable waste management, the Australian mining and steel industry is proactively seeking large scale recycling schemes for coal wash and slag. If the construction potential of these wastes is favourable for reclamation, then the environmental and socio-economic benefits will be substantial due to less quarrying of fresh rock and reduced volume of waste tips on otherwise usable land. The research outcomes will be published in peer-reviewed journals and conferences, raising Australia's scientific profile in granular waste management. The geotechnical community will benefit through the rigorous training of professionals, while industry hosted seminars will promote the dissemination of knowledge gained to practitioners.Read moreRead less
